1 Introduction

Thank you for the trust you have proved to us with the acquisition of this product. The Sommer Informatik GmbH has put quality as the highest aim to itself and will also put in future everything in it to present high-quality software to you. Before a product leaves our house, it is tested extensively and checked conscientiously. Still we cannot exclude program error completely. For program-technical mistakes and mistakes in the results every liability is excluded. We ask you to inform us about possible mistakes, so we can repair this as fast as possible and hand over a free update to you. Of course we are also very grateful about other suggestions and improvements. So we can extend the functionality and service constantly and improve, where you certainly can profit in later versions..

With the Windows application WinIso 3D you can calculate three-dimensional stationary heat flows for cross sections. The calculation delivers the length-related whole warmth stream and temperatures which can be questioned point-wise or be shown as isotherms.

Following problems can be solved separated or combined:

The heat losses are generated only by the inside and outside climate,

there are additional heat flows, e. g. heating (firm preliminary heat temperature, calculation of the loss of heat),

there are additional heat flows, e. g. the sun (firm warm increase, calculation of the temperature).

The calculation of the temperatures bases on the method of the finite elements (FEM). For the software friendly calculation of the problem the desired area is splitted in accordingly small sub ranges - finite elements - and assigns to every element (cell) the suitable material, i. e. certain qualities according to the heat. With different edge terms the heat flow equation is solved for every finite element separately. The finite element problem again is calculated on a modified Gauß-Seidel-Iteration.

The achievement borders of the program are determined by the arithmetic exactness and the program-technical exactness. The exactness of the calculation after the FEM depends in the essentials on the delicacy of the elective line column grid and on the heat identity values (warm conductivity, transitional resistance...). It must be also considered that FEM is a mathematical model.

The program limits the division of the project in finite elements by the smallest possible element dimension of 0. 01 x 0. 01 x 0. 01 mm, as well as by the maximum-possible division in 400 x 400 x 100 cells (x y z). A project can be divided at most into 16 million elements and arbitrarily many materials can be used.



The elements can show up following characteristics:

• Adiabatic elements

• Elements described by their heat transfer coefficient α (e.g. inside/outside air)

• Elements described by their heat conductivity λ (e.g. wood, glass)

• Elements which get assigned a certain theoretical warm insulating value (e. g. enclosed air whose warm-technical behavior is more complicated by convection and radiation and is determined externally).

2 Installation

2.1 System requirements The installation program copies files of the CD (or from the ZIP folder) on the hard disk of your PC.

It has an informational property. You can move the bar to any position. It is consists of the project materialist and three text fields. Project materiallist: You can find all materials in the project material list which are defined in the current project. In a new project, you have to selected all materials which should be used in the new project from the material database. The list can be enlarged at any time. Textfield 1: This field has two different meanings. In case of your cursor being in the ruler area, the distance to the beginning of the project is displayed in mm (top left). If the cursor being in the project area an one cell is selected, the current temperature of the cell is displayed. Textfield 2: This field also has two different meanings. In case of more cells are selected and the cursor is in the project area, the size of the smallest rectangle is displayed (b: breadth h: height). You can measure the distance between two cells in this way. If your cursor is in the ruler area, the distance between two nearby grid lines is displayed.



5 Edit project There are different ways to edit a project in WinIso3D.

• Import of a 2D-File • Own definition of a grid and a filling directly in the editor

5.1 Number of nodes You can control the maximum node number with the dialogue knot number. This is accessible by the menu point Options>>Number of nodes... After a change of the node number you must restart WinIso 3D, so the program with the new node number is initialized. Please remember the fact that the more nodes you select, the more memory the program needs.

Moreover, the node number is dynamically steered. If enough main memory does not exist for the preset node number, the nodes are automatically adapted to the available main memory.

5.2 Open an existing project

Via File>>Open or in the toolbar you can open an existing project.

Hint: existing projects have the file ending .w3d.

This can arbitrarily be edited. Therefore you can go to chapter 6.3



5.3 Navigation through a project in WinIso3D

5.3.1 General The program WinIso 3D calculates three-dimensional heat flows. To be able to define a three-dimensional project, an input on two-dimensional way must take place. The three-dimensional project is shown disc-wise in a two-dimensional view. That's why a relatively uncomplicated input is possible. The single levels can be controlled through the dialogue view or through the key picture up or picture down. The following three views from the technical drawing area were taken over:

- Front view - Side view - Plan view

5.3.2 Dialog View The dialog view is a visual navigation help between the single planes of the project. It becomes opened or closed with the menu point View>>Dialog view. The dialogue is a non-modal window that means inputs can be made furthermore in the main window.

Through the radiobuttons front view, side view and plan view can be steered by the single views of the project. The depth of the topical view can be regulated by arrow up and arrow down or by the vertical regulator. There is also the possibility to go to a level by entering the number of the level. The cube should show the topical cut view visually.

5.3.3 Cursor The cursor is a navigation point for the project with its different levels and views. The current position of the cursor is visualized as a kind of grid on the cell.



The cursor is seen as a kind of anchor in the project. If you are on another level and you want to go

back to the level with the cursor, you just have to click the button ( ) and the level will display.

5.4 Define a project The program WinIso 3D calculates three-dimensional heat flows. Therefore the single cross sections of the object to be calculated must be defined in the project area. The project exists exclusively of horizontal and vertical orthogonal lines. The single cells are unambiguously defined by these grid lines. Afterwards the cells must be filled with the suitable materials. You can change the size and filling material of the cells at any time.

5.4.1 Select material / material database To fill your forms (CAD-Lines) with materials, you have to adapt materials in a selection list. This may be confusing but it makes you project more clear.

First open your database with the menu point Material>>Material database, or you click on the

toolbar icon .



On the left side are installed global material records. On the right side of the material database the materials to be used ("project materials") are put together. These appear while closing the material database (with click on OK) in the main window in a drop down list. The project materials can be put together by double click on the global materials or by pretending and shifting with the arrow button on the right. The materials ND and ADIABAT are always available.

ND = not defined ADIABAT = Material with endless high thermal resistance.

Hint: The usual materials for windows and facade are in the material group "2_EN ISO 10077-2". Material of the group "2_EN ISO 10077-2" are write-protected and cannot be changed. If these materials are used, the word export functions offer an automatic check of the norm conformance of the materials.

Therefore it recommends to provide a model in WinIso2D first, where you set the "10077-air" in this and to substitute according to the calculation with an equivalent spare solid afterwards. Besides, the warm conductivity can be read in main heat flow direction by activating the info window. Alternative you can calculate like in EN ISO 6946 or EN 673.



5.4.2 Edit Grid/Rows/Column

5.4.2.1 Define cells To define a new project, you must first fix the geometry with the help of the vertical and horizontal grid lines. You can do this while you position the cursor at the desired place in the ruler area and press the CTRL-key at the same time with the left mouse key.

5.4.2.2 Narrow down a grid in areas without partition To guarantee an exact calculation areas which are divided coarse, or are not divided at all, have to be divided by hand. For this, mark an arbitrary cell in the project area with left mouse click. Select Edit>>Automatically split from the menu bar (or CTRL+F4).

Additional nodes are created. This can be seen in the ruler area.

Because the automatic grits were developed for 2D, a manual adaptation is necessary here in 3D. It is recommended to provide the model in the minimum grid and to do necessary adaptations by the treatment individually. See in addition in the following chapter 6.4.2.3

5.4.2.3 Split row/column There is still another possibility to insert a grid line between two already existing grid lines. Select one or several cells and then choose the menu point Edit>>Row splitting or Column splitting. Now in the dialogue field you can determine the position of the new grid line in relation for both neighboring grid lines. Then the new grid lines are inserted in the lines or columns in which at least one cell was selected. Afterwards the selection moves accordingly.



Shift + F5 F5

5.4.2.4 Edit row height/column width You can change the height of lines and the width of columns any time. In addition at least one cell must be selected in the line or column. Via menu points Edit>>Change row height (F6) or Edit>>Change column width (Shift+F6) you can select the new parameters. In the text field you can see the current parameters.

Shift + F6 F6

With the mouse you can also change the size of a line or column very fast. Point with the cursor at the grid line, click on the left mouse key with pushed SHIFT-Button and draw the grid line with pushed mouse key to the new position where you can place the grid line then. All following grid lines have moved around the same value, so that only the size of one line or column has changed. If you have filed the grid line beside the upper or left neighbor, the line or column has the new size of 1 mm. If you move a grid line with low-spirited right mouse key, only the splitting changes, i. e. the size of directly affected lines or columns is changed. If the grid line was filed beside the upper, lower, left or right grid line, the suitable line or column also has the size of 1 mm.

Hint: Pay attention by changes with the mouse to both text windows in the symbolic strip which indicate the absolute distance at the project beginning and the relative distances to the neighboring grid lines.

5.4.2.5 Combine rows/Columns If the cells are defined by two neighboring lines or columns in each case with the same materials, the intervening grid line can be extinguished. Both lines and columns are combined to a line or column (reverse action to splitting). Therefore you point at the suitable grid line, click those, move them with low-spirited left mouse key and SHIFT from the ruler area and then file them. With an ineffective union, an announcement will take you notice of it. Then the grid line is inserted in the old position again. This action can be also explained with the right mouse key. This function can be also explained about the menu. Therefore a cell must be selected first. Afterwards the program after choice of the function Edit - combine line / column the line / column in which the selection is , is combined with the ones in the upper or left line / column. If several cells are selected, the order refers to the cell selected first of all. It is carried out always only one union. About the menu point of Edit-minimum



grids you can run all unions permissible in the project in the lines as well as in the columns all at once. This action can be cancelled with Edit - Undo again.

Attention: in 3D there is not the possibility to undo the splitting or combining by typing CTRL+Z. Save your project from time to time to go to a earlier editing in case of problems.

5.4.2.6 Delete rows/columns You can extinguish one or several lines or columns from the project. Mark in each case at least one cell which is in the line or column to be extinguished. Afterwards you choose the menu point Edit-Delete row (F7) or Edit – Delete column (Shift+F7). Please remind the difference to combine rows/columns.

5.4.2.7 Insert rows/columns Here you mark a cell of the row or column, about or before, where a new one should be inserted. With the menu point Edit - Insert row (F8) insert or Edit - Insert column (Shift+F8) you can insert a new line or column in the project.

5.4.3 Select material At a self created grid in WinIso 3D you have to fill the grid with material. This has to be made for every level. The best way is to use the view with the lowest number of levels and click systematically from level zero till the end.

It is most clear if you first fill solids, afterwards the inside and outside climate and at last the hollow cavities with materials.

For easier navigation remind chapter 4.1.1 and 5.3

5.4.3.1 Fill cells First choose a material from the project you defined before. Select one or more cells and fill them

with the selected material or by clickling , with F2 or with a right mouse click in the single cells.



5.4.3.2 Fill area Coherent surfaces can be filed regardless of the grid lines with another material.

Hint: To the better overview you are able to do coherent surfaces, with click on in the toolbar. They get a black outline. With a second click you can undo the outline.

To show or hide the grid lines click on View>>Visualization>>Grid full

Step 1: Select material in drop down list.

Step 2: Select a single cell with clicking left mouse button. More cells can be selected by holding left mouse button.

Step 3: Fill selected cells with in the toolbar (or F2, or Edit>>Fill selected cells)

5.4.4 From 2D to a 3D project The use is easier with more complicated details if the project is defined in WinIso2D and is imported in WinIso3D afterwards. For the treatment in WinIso2D you follow please the separate manual.

You can load an existing 2D file with File>>Import WinIso2D file or CTRL+Shift+l

The selected file is opened as a new 3D project. The dialog view has to be opened new by clicking

. The 2D file should be saved with minimal grid before.

The 2D file is made as a front view with the length 1000mm. To bring the cut in the right view it has to be rotated a bit.



Example: Horizontal cut through a wooden window frame profile

1. Insert position



2. Change to side view

3. Rotate the view 90° with Edit>>Turn>>90°

4. Change to plane view



5.4.5 Add objects

5.4.5.1 Alternative 1 „Copy and Paste“ This method doesn’t work in the 3D editor. Please use the function File>>Import WinIso2D object.

5.4.5.2 Alternative 2 „Import“ This function offers more options than „Copy and paste“ with the insertion. For example, the object to be inserted can be turned round the import point, or be shone.

Step 1:

Mark the cell where you want to import the object.

(always the top left one)

Step 2:

Import of a saved WinIso project with the function File>>Import WinIso2D file. Now you have to select a file which contains the object you want to insert. If you chose a file it will be imported and a window displays where you can set the options for the import.

5.4.5.3 Information for import The object is inserted only in the chosen layer. If several layers exist, the object can be inserted several times.

During the insertion missing grid lines are automatically generated. If the project crosses the maximum number of the elements, you are drawn the attention by an announcement. In this case the object is not inserted. The objects which were provided with the DOS program Isotherm cannot be inserted. All materials of the object which do not exist in the project yet are taken over in the project data bank. If a material exists in the project as well as in the object, is checked whether both



materials are identical. If at least one material quality is not the same, the material is incompatible and following dialogue window is opened:

You can take over the suitable material with the material qualities to the current project (option button "keep") or define the material by another name under which it is inserted then in the project (option button "take over").



5.4.6 Edit levels Change to the view where you want to edit. Keep in mind that you always just edit the current level.

Example: Make window profile to the corner of the window

Top view Side view Front view

In the front view you are able to edit level to level.

Plane 0 is the inside air, here nothing must be adapted. Plane 1 available materials go „on edge“ around the corner. Moreover it is advisable to go from the left to the right by the layers and to fill the heights with F5 and split according to the thickness and to fill the cells. You repeat this step for all planes.

New Planes are created according to the splitting in the top view.



6 Calculation

6.1 Before calculating Before you calculate the program it has to be splitted. The easiest way is to do it manual with pushed CTRL-button and the left mouse click.

Here it must be split in all views individually. Every material plane should be arranged at least by 2-3 elements.

The whole cutting should be chosen large enough for a consistent result. (In our example about 1 m x 1 m)

Split at first roughly the front view

Go through your cuts after details and split all material planes and crossover in the different views.



6.2 Select calculating parameters With the menu point Edit calculate parameters you can set some frame conditions which take influence to the calculation.

Autorelax:

The relaxfactor speeds up the calculation. This factor is determined new after every calculation with the selection button Autorelax.

Ralaxfactor:

With this choice button the Relaxfaktor can be also selected by hand. Interrupt the calculation and put new values in the input field. Nevertheless, the choice of the right Relaxfactor requires some experience. With a choice of an unfavorable value the calculation can become unstable.



Convergence demand and temperature change:

This value is a criteria for the abortion of the calculation and sets the width of the temperature in 10-³ °C (1mK). In every flow of the calculation loop this span is new calculated. After every calculation loop the at last calculated span of the temperature change is compared to this value. If this value is reached or fallen short, and is also the convergence demand for the relative heat flow change, the calculation is finished.

Convergence demand relative heat flow change:

This value is another criterion for the abortion of the calculation and gives the relative difference between the supplied and delivered heat flow. After every calculation loop the calculated value is compared to this value. If this value is reached or fallen short, and is also the convergence demand for the relative heat flow change, the calculation is finished.

Temperature depending values:

Every project can be calculated with identity values independent of temperature or dependent on temperature. The calculation with identity values independent of temperature is normally executed. Thereby the program is always calculated a second time after the first calculation (2 iterations). If you want to calculate identity values dependent on temperature, you can fix in the input field the number of iterations, how often the calculation should be executed. This kind of the calculation is a special case and is not used regularly.

Number of runs:

This value says how often calculation runs will run through, until the worth K, relax, dt and dq in the dialogue supervise calculation are updated. In every run the temperatures are new calculated for all elements with variable temperature. The smaller this value is, the more exactly the calculation can be followed or influenced.

During the calculation you can supervise in the dialogue calculation pursue the development of the calculation and if necessary interrupt or finish. To change the calculation parameters, you must interrupt the calculation before. The control of the relaxfactors is also possible during the calculation.



The input field Calculation steps defines the number of calculation runs. In the logarithm coordinate system the development of the calculation is described with following values:

k: Current run of the calculation loop. relax/autorelax: Current value of the relaxfactor. dt: n Width of the temperature change after the last calculation run. dq: Relative difference between the delivered and discharged heat flow after the last calculation run. This value is indicated graphically by the red beams in the co-ordinate system. The convergence behavior of the calculation can be pursued well. *** x. RUN *** Current calculation run (Iteration). Hint: By calculation with gases which are defined as user def. the surface emissivity is not considered.



6.3 Start calculation

Start the calculation by clicking on in the toolbar or via Calculate>>Start with reset of project.

7 General evaluation

7.1 Cell information

By clicking in the toolbar, an information window is opened which contains information of the selected cell.

Headline: Number of column and row(horizontal distance of the beginning of the project, vertical distance to the beginning of the project), material number (cell width and height) Material, temperature of the cell, heat flow and heat conductivity in x- and y-direction are displayed in the current section.

If more cells are selected with Shift and the cursor button, the field T shows the mean temperature and the field Q the sum of the heat output.



7.2 Information about project materials You can find out about the menu point Material - info about materials... about all materials used in the project closer. The whole volume which takes the material in the project as well as the whole heat flows are displayed.

The sum of all heat flows Q should be zero, otherwise the project isn’t splitted enough detailed.

The sum of all heat flows of one algebraic sign is the total heat loss of the selected area. With these values a punctual heat bridge can be calculated by hand.



7.3 Visualization

7.3.1 Visualization of temperature fields

This visualization is suitable only after a calculation. Via in the tool bar or the menu point View-Visualization-Temperature fields you are allowed to indicate the topical temperature distribution in the project.

Therefore the topical temperature of the material is shown for every cell instead of the colour of the material in colour. You can change under the menu point Options>>change colour between a false colour representation and a blue-white-red-visualization.



With the menu point Options – Range of values - Temperature... you are able to define the range of temperature. All temperatures beyond this interval are shown white.

The three option buttons have the following meaning:

• Fixed interval from -20 °C to +20 °C.

• Interval is based on the lowest and highest temperature in the project.

• You can define an interval by yourself.

The editing field Step has no meaning in this connection. The suitable temperature scale to this interval can be faded in via View - Visualization - Scale.



7.3.2 Visualization of heat flow fields Just as with the temperature representation the project should also have been also calculated here.

With the toolbar button or the menu point View – Visualization – Heat flow you can display the current heat flow in your project. In every cell the current heat flow is indicated in colour. Here you can also choose between a false colour representation and a blue-white-red-visualization and fade in a suitable scale.

You can also define the interval with the menu instruction Options – Range of values – Heat flow. All heat flows out of this interval are shown in white.

The three option buttons have following meaning:

• Fixed interval from 0 W/m² to 100 W/m².

• Interval is based on the lowest and highest temperature in the project.

• You can define an interval by yourself.



7.3.3 Visualization of isotherms For the better evaluation of the calculated project you can also indicate the isotherm lines which are to be seen in each of the representations described on top. Activate the isotherm lines with click on

in the toolbar or the menu point View - Isotherms.

With the menu instruction View>>Visualization>>Without fields you can fade out material fields.

You can change the settings via Options>>Range of values>>Isotherms.

Three option buttons have the same meaning like with the visualization of the temperature fields. In addition, you can also fix the step width. E. G. , min-15 max. +20 step 5

Note: -15, -10, -5, 0, 5, 10, 15, 20

Hint: About the menu point View>>Inscription>>Temperature isotherms the temperature is indicated to every isotherm line. You can define with the order Options>>Line width isotherms... the pixel width of the isotherms.



In the uppermost input field you can fix the pixel width with which all isotherm lines are shown whose temperature line is in the defined interval (Options - Range of values - Isotherms...). In addition, the announcement from up to three special isotherm lines which are also in the defined area can be fixed. Therefore select the temperature and the desired pixel width in the input fields under Exceptions. The besides used colour is behind it in clips and cannot be changed. If you give the value 0 as a pixel width, the width defined on top with the topical colour is used to the representation of the isotherm line for the isotherms. If you like to show blue, e. g. only 10 °-isotherm lines in the width of 3 pixels and the colour, then you give in the second line the suitable values and put in the first and third line the pixel width on 0.

7.4 U-Value With the instruction Tools - U-Value (Alt+F2) or the button you can calculate a linear U-value in the project. Therefore a cell must be selected with variable temperature by which the U value goes through. If several cells are selected, the cell selected last is used for the calculation. Then the program checks whether the U value can be determined obviously, which means whether the cell is between a heat source and a heat sink. If this is the case, the corresponding U value is displayed in the dialogue field an additional in the project are through a red horizontal or vertical line.



7.5 min. /max. surface temperature

With the command Tools – min./max. button the minimum and maximum temperature is calculated for the view of the current project fRSI=(Tsi - Taußen) / (Tinnen - Taußen) and displayed with the manual inscription.



7.6 Evaluation of special windows

8 Print project

8.1 Print current project (without details) With File>>Side view you can get a view of the project part which is then printed out with File>>Print (or CTRL+P).

The so generated graphics can be further used separate. So you can fastly input the generated pictures in the existing model.

By clicking in the toolbar the shown part of the project can be put into a buffer and pasted more times in the model.



8.1.1 Individual control of the print

8.1.1.1 Printing options In the menu Options - printing settings the expression of the project can be defined. So you can fix which components should appear in the later expression and which not.

Edge settings can be defined where you can shift either only the project area or also the legend with materials, date etc. to the right or below. The following dependence between the topical project view and the pressure options exists:

The in each case inactive options can be neither changed nor be printed out. To the control the print format about the menu order File - Side view should be checked before printing and if necessary be changed afterwards.

Behind the material name the conductivity L or the transitional opposition R of the suitable material is additionally given. Moreover, the name of the licensed company is given in the lower edge. Now in the legend, in the lower edge of the expression, the Qtotal - value is printed out in addition.

View Material Scale Material fields Active Inactive Temperature fields Inactive Active Heat flow fields Inactive Active Without fields Inactive Inactive



8.1.1.2 Size of the graphic in the printing It is possible to make the size of the printing bigger or smaller. You can get to this setting with Options – Print.

The factor is fixed by shifting the regulator in the field Size of the graphics for the enlargement or reduction of the graphics. A value between 0 and 1 reduces the graphics. Values more than 1 increase the expression. The value 2 corresponds of the double ones, the value 10 to the tenfold size of the graphics in the expression.

8.1.1.3 Additional text information In the menu File information... the possibility exists to define 3 lines with at most 70 signs in each case which appear if requested in the project printing.

Every line can be centered individually flush left, or be formatted flush right. If the information should be printed, the controlling small box INFO LINES must be activated under the menu point Options - printing. The printing position is above the material announcement or above the temperature or heat flow scale.

8.1.1.4 Mix colour and hatching of the printing In the material data base you can assign to every material a freely eligible colour as well as one of 20 firmly defined shadings. During the editing on the screen the possibility exists to switch over between these both representations. The single cells are filled either with the colour or with the shading of the suitable material.

For the project printing the possibility insists on mixing these both representations. About the order View>>Visualization>>Colour / hatching (printing) can fix for every project material how it should be shown in the printing.



A material can be defined on the printing either with that colour, with the defined shading, black or white. In addition the material must be selected first in the list field on the left. Afterwards the representation is fixed by the choice of the suitable radiobutton on the right. With the both buttons under you can fix for all materials whether these are printed out only in colour or only in shading.

The following picture shows a printing where some materials are displayed in colour and other ones in hatching.

These settings are just according to the printing and doesn’t change the project itself.



8.1.2 Manual inscription With the right mouse key the topical project can be marked for later presentations quite individually. There is the possibility to define new texts, to work on available texts or to shift. In addition, all inscriptions can be faded in or faded out according to demand. With the memory of the project all defined inscription texts with the suitable qualities and the position are saved in the project.

8.1.2.1 Insert inscription With low-spirited CTRL key and also low-spirited right mouse key a new inscription text is inserted in the topical project. Therefore in the dialogue manual inscription the creation of the text has to be fixed.

You can fix the text, the text colour and the type-size. Moreover there is the possibility to define the text clear and with connecting line between the text position and the relation cell. The relation cell is always the cell on which the mouse was with the mouse click. The relation cell as well as the text can be shifted later to another position. The inscription text can be defined of course also regardless of the relation cell (e. g. editor, date, project description...). Then, however, no connecting line should be indicated. If no text is defined and OK is pressed, the dialogue shuts without changes.

In both fields under current cell values the current temperature and the current material name of the relation cell is indicated. With both controlling boxes in contents these values can be taken over in the text field or be extinguished again from the text. Of course the contents of the text can be changed arbitrarily, even if one or both controlling boxes are activated.

Both fields, if activated, have one more meaning:

If the text contains the material name or the temperature of the cell, this is updated by a change of the cell immediately. So, e. g. the name is updated if the cell is defined with another material . According to a calculation the new cell temperature is automatically updated in the text, if the old temperature was indicated before.

8.1.2.2 Edit inscription If the cursor is on the first or second sign (catch area) of an inscription text, this can be worked on by concurrent pressure of CTRL and the right mouse key. In addition the dialogue described on top with the topical settings is opened. It is also possible to change the inscriptions about the menu point View - Inscription - Manual inscription. In addition the following dialogue is opened, with the defined



inscription on the left side can be edited with the button CHANGE. Alternatively you can also doubleclick on the desired entry. Afterwards the dialogue described on top with the topical values is opened. In addition, the possibility exists to extinguish one or all inscriptions from the project.

All changes are updated by clicking OK.

8.1.2.3 Move inscription If the cursor is like while changing on the first or second sign (catch area) of an inscription text, this can be shifted with low-spirited SHIFT key and low-spirited right mouse key to any position in the project area. However, the relation cell of the inscription can be also changed. In addition the cursor must be in the relation cell. Afterwards the end of the connecting line can be shifted with low-spirited SHIFT key and at the same time low-spirited right mouse key to the new relation cell. With active controlling box temperature or name the inscription text is adapted immediately to the new relation cell. One end of the connecting line is positioned always automatically in the middle of the relation cell. For the same relation cell several inscription texts can be also defined in different positions.



8.1.2.4 Font settings for the printing You can change the settings by clicking on Options → Print font…

8.1.2.5 Set font for manual inscription You can assign an own font to every manual inscription. The font is put as follows. Hold the control key low-spirited and click in the drawing on the desired position, with it you receive the following dialogue box:

With the button Font style… you can change the font in a dialogue box as you did it with changing the font for the printing.

8.1.2.6 Fade in/out inscription With the menu instruction View>>Inscription>>manual inscription you can show or hide the inscription of the whole project at any time.



9 DXF-Exchange files

9.1 What are DXF-Exchange files? It is often the case that files which e. g. were prepared with AutoCAD or another CAD system are continued to work on by other programs or that programs prepare files which are then fed and continued to work on with a CAD program. To make the exchange of drawings possible between different computer systems and to provide application programs with CAD data, the drawing exchange format DXF was defined. DXF files are standard ASCII text files. They can be translated in the format of CAD systems easily or be processed by other programs for the purpose of special analyses. All implementations of AutoCAD accept data in this format and are able to convert these data into an AutoCAD database and the other way. You can both feed (import) and produce from the current project DXF files with WinIso 3D (export).

9.2 Import DXF-File You can generate a drawing exchange file with the command DXFOUT from an existing drawing in AutoCAD. You are able to load a DXF file via the menu point File - Load DXF in WinIso 3D after you have opened a new project feed and cannot continue working. Lines (vertical, horizontal, diagonal) and quarter circular arcs can be fed. The circular arcs are shown as right angles. All other drawing elements are ignored. The coordinates are interpreted in millimeter and a grid line arises from any imported line. In the dialogue window Selection Layer you have to mark from which layer the lines should be imported. More selections are possible.



10 Hints for faster calculation Control the calculation parameters by clicking on Calculate>>Edit parameters… in the menu bar.

With the convergence requirements you define when the stationary condition is achieved for the program. Change the presetting here only very carefully (like in the right picture) when you are conscious about the consequences for the result precision.

The calculation process is at the fastest if you make sure that you are in the material country area and isotherms etc. is turned off for the time before the calculation start. You see this that only the badge material fields is pressed in as represented in the right picture.

Many computer, particularly laptops have integrated a power management program in the operating system with which possibly the processor achievement is throttled (mostly under system control>>energy options). If you raise the processor achievement, the calculation time will be shorter.

Because of the same value of the normal 𝑅𝑠𝑒 -value (𝑅𝑠𝑒 = 0,04𝑚2𝐾𝑊

) and the 𝑅𝑠𝑒 - value for

radiation/convection (𝑅𝑠𝑒 = 0,04𝑚2𝐾𝑊

), these good ventilated cavities have to be set with air

outside 0.04, 0°C, 80%.

Because of the value inside for 𝑅𝑠𝑖 (𝑅𝑠𝑖 = 0,13𝑚2𝐾𝑊

) isn’t the same like the 𝑅𝑠𝑒 - value for

less radiation/convection (𝑅𝑠𝑖 = 0,20𝑚2𝐾𝑊

) you have to set those cavities with air inside 0.20,

20°C, 50%.

Further, inside corner areas can be seen as areas with less radiation/convection (𝑅𝑠𝑖 =
