applications in MSC.PatranUnderstand Analysis Application as

both an Import & Export tool for FEM dataLearn Results procedures to insure

that displayed MSC.Patran results are THE SAME as MSC.Nastran .F06 printed results

MSC.Patran Analysis ApplicationMSC.Patran Analysis Application Transition Application between Pre-processing

& Post-processing tasks in MSC.Patran Application functionality tailored based on the

Analysis Preference selected for the MSC.Patran database

Management of:Analysis Jobs & Associated FilesResults ImportModel Import

Data stored in the Analysis Application (as well as the Results Application) are not imported to other MSC.Patran databases during File/Import, Source=MSC.Patran DB

MSC.Patran Analysis ApplicationMSC.Patran Analysis ApplicationStandard MSC.Patran AOM FormActions Available:

(MSC.Nastran)

Form Functionality changes dependent on Analysis Preference chosen for a given MSC.Patran DatabaseNote the Code/Type/Study Indicators

Analysis: AnalyzeAnalysis: Analyze

4 Objects AvailableEntire Model: Will export an Analysis model of

EVERYTHING that is in the database, regardless of what is posted to the current viewportSelected Group: Will export an Analysis model of

a selected group in the Patran dbExisting Deck: Instruct MSC.Patran to submit an

Analysis of an existing MSC.Nastran deck by simply selecting the Analysis Job NameRestart: Set up a Restart Analysis deck using an

existing Analysis Job Name & creating a new Restart Job Name (supported for SOL 101, 103 & 106 only)


Depending on Object selected, up to 4 Methods available:Full Run: Exports a run-ready MSC.Nastran

analysis deck & submits it to the version of MSC.Nastran selectedAnalysis Deck: Exports a run-ready MSC.Nastran

analysis deckModel Only: Exports only a bulk data MSC.Nastran

deck (no FMS, Exec, or Case Control commands)Check Run: Exports a run-ready MSC.Nastran

analysis deck with PARAM,CHECKOUT,YES and runs the Checkout job in the version of MSC.Nastran selected

Analysis: AnalyzeAnalysis: AnalyzeJob NameImportant tool in the Analysis FormServes several purposesPrefix name of Analysis deck, and resulting Analysis files

generated from MSC.Nastran (jobname.bdf, jobname.f06, etc.)Name stores all the settings on the Analysis form used to

generate the job from MSC.Patran to MSC.NastranCan create a job description that tags along with job

name in the MSC.Patran database for future referenceServes as a cross-reference link when importing results

between database stored subcase / load case names and result file subcase / load case names

Be careful when deleting job namesall associated files generated by that job name in the database directory will also be deleted


Translation ParametersSpecify type of results output

desired (PARAM,POST)XDB w/ or w/out .F06 outputOP2 w/ or w/out .F06 output .F06 output onlyNone

Default is XDB & PrintDefault can be changed via

settings.pcl commandpref_env_set_string(NastranResultsOutput,

OP2 and Print)See Part 1, Section 5.2, page 120 for all

available options


Translation Parameters (cont.)TolerancesUsed for numerical manipulation during export

translationDivision tolerance prevents divide by zero errors

(default 1.0e-8)Numerical determines if two real values are equal

(default 1.0e-4)Writing determines when a field entry is

approximately zero (default 1.0e-21)This is one of the reasons why 0.0 may be written as

2.6e-14


Translation Parameters (cont.)Bulk Data FormatOption to have MSC.Patran output sorted or unsorted Bulk

data (not the same as ECHO=SORT, which can be set in Solution Parameters)Card format set to Either by defaultmay set to Small

or Large (8 or 16 character field, respectively)Either usually outputs Small field formatGrid Precision Digits is used to control number of precision

digits after the decimal to output Grid card valuesGPD properly accounts for rounding (no truncation)Can aide in maintaining values like 0.0 or 15.0, and not

changing them to 2.6e-14 or 14.99999999, respectively

Analysis: AnalyzeAnalysis: AnalyzeTranslation Parameters (cont.)Node Coordinates: Specify what

coordinate frame (reference, analysis, global) the grids are to be written into (CP field on the GRID card)MSC.Nastran Version:Tells MSC.Patran to export cards

appropriate to the version of MSC.Nastran specified (2001, 70.7, etc.)Tells MSC.Patran which version of

MSC.Nastran to use on a Full Run method

Number of Tasks: If using MSC.Nastran Parallel option, specify number of processors to distribute the job


Translation Parameters (cont.)Write Properties on Element Entries: Switch allows export

of combined element/property cards, such as CELAS2Write Continuation Markers: Off by default, this switch will

produce continuation markers that can be defined/customized in the numbering options button on this formConvert CBARs to CBEAMs: New switch to take all CBAR

property cards and convert them to equivalent CBEAM cards. Useful for converting models from SOL101 to SOL106Use Iterative Solver: When MSC.Patran is used in Full

Run mode, it will submit the analysis deck with MSC.Nastran flag, ITER=YES (also done by SYSTEM(216)=1)


Translation Parameters (cont.)Numbering OptionsOpportunity to offset numbering for

anything ranging from GRIDs to PIDs for PropertiesCan specify your own starting

symbol for a continuation markerSet Encoded Syntax Format

Default is to take any Property, LBC, or Material Name that has a . in it, and use the trailing number as the corresponding PID, MID, etc.

On by default If you get a message about

conflicting encoded ids, you can turn Encoded Syntax off, or you just need to rename the set causing the conflict


Translation Parameters (cont.)Bulk Data Include FileThis button allows 1 MSC.Nastran Include File to be

added to the Analysis Deck being ExportedIf more than 1 Include File is to be included with the

Exported Analysis Deck, the Include statements must be manually added in the appropriate section of the Direct Text Input form (to be discussed later)

Analysis: AnalyzeAnalysis: Analyze Solution TypeChoose the Solution Sequence to be

executed by MSC.NastranSolution Parameters change according

to the Solution Type Certain Solution Parameters include

MSC.Nastran Bulk commands like:PARAM,WTMASS,.00259PARAM,GRDPNT,15PARAM,K6ROT,10.0PARAM,SNORM,20.0

Additional Solution Sequences can be invoked depending on Solution Parameter settings, such as Cyclic SymmetryUnstructured Solution Sequences

(SOL1) can be invoked by turning off the Database Run switch


Direct Text InputThis allows a user to input commands into

sections of the MSC.Nastran Analysis Deck that would not be exported by MSC.PatranCommands may be entered in FMS, Exec, Case

or Bulk Sections of the DeckReject cards from a MSC.Nastran Deck

import may be exported to a newly created deckNOTE: Text/Commands input to DTI will be

placed at the beginning of the appropriate section of the deck. The user has no option to insert commands at different locations of an Analysis deck region

Analysis: AnalyzeAnalysis: AnalyzeSubcasesIn MSC.Patran, a Subcase is the

union of a Load Case, Subcase Parameters, Output Requests, SE definitions, & Selected Explicit MPCsThis differs from MSC.Nastran

terminology where a Subcase is a combination of LBC sets, output requests, and SE definitionsThe two methods, however, are

equivalent!!!For Every Load Case created in a

MSC.Patran database, a Subcase is AUTOMATICALLY created (defaulted 1:1 correspondence)

Analysis: AnalyzeAnalysis: AnalyzeSubcase Creation:Even though there is a 1:1 correspondence

between Subcases & Load cases, you may want to create a new SubcaseAfter creating/selecting the Subcase name,

optionally type a description of the SubcaseAssociate a Load Case to be used for this

Subcase (if you select an available Subcase, you will notice that an associated Load Case will be already highlighted)Proceed to select appropriate Subcase

Parameters, Output Requests, DTI, SEs & Explicit MPCsHit Apply & Cancel when doneSubcase is activated for the Analysis deck

to be exported via Subcase Select


Subcase Output RequestsTwo ways to specify

Output RequestsIndividually via Subcase

Create: Output RequestsFor multiple Subcases with

same requests, go to Subcase: Global Data

Analysis: AnalyzeAnalysis: Analyze Output Requests: 1 SubcaseTwo types of form: Basic &

AdvancedBasic simply allows you to pick a

Result type & accept the defaults on the output requestAdvanced is the double form shownSelect a result type for the chosen

SOL type and choose the appropriate options for the output request, including whether to output results to the .F06 fileAny group you create can be used

as a MSC.Nastran SET. You dont have to output results for all entities!!!Hit OK on this form and Apply on

the Subcases form to save the changes


Output Requests: Multiple SubcasesSubcases: Global DataSelect the Subcases that will be

getting the same output request data & click on Output Requests buttonSelect column or individual cells

where you want output specifiedSelect SETs, where appropriate,

along with Output Request optionsClick on OK in middle of form to

insert Output Request Command to cell(s)When finished with Spreadsheet, hit

OK on panel shown on right, and Apply on Subcases: Global Data form

Analysis: AnalyzeAnalysis: AnalyzeNotes on SubcasesWhen Deleting Subcases, they must not be

associated to any existing Analysis Jobs. If they are, they wont be deleted until the association is brokenWhen choosing Subcases (using Subcase

Select), there is an option to select all or unselect all for easier selectionMSC.Patran focuses on the SUBTITLE card in a

MSC.Nastran deck. MSC.Patran does not use the LABEL card, which is typically used by MSC.Nastran in a Subcase block

Analysis: OptimizeAnalysis: Optimize

Used when performing SOL 200 Analyses (MSC.Nastran Design Optimization

Form knows that SOL 200 jobs use other SOL sequences (SOL 101 & 103 supported by MSC.Patran) as Subcases

Form essentially same as Analyze form (no Restart functionality)

Build Model as usual, but define Model Variables & Design Studies before going to Analysis (Tools menu)

Current Model Study shown on Analysis: Optimize form


Optimization ParametersUses all the Defaults

defined by MSC.Nastran for SOL 200 analysesGood Defaults given; not

usually much need to change them (other than # of Design Cycles to be computedDESMAX)


SubcasesForm generally the same

except that Subcases are built upon Solution Sequences 101 or 103Global Data not available for

Optimization Analyses


Subcase SelectChoose Subcases to be

run in order and in terms of Solution Sequences which they were createdSOL 101 or 103 Supported

Otherwise, same functionality as Analyze-Subcase Select

Analysis: DeleteAnalysis: Delete

There are two types that can be Deleted from the Analysis Application:Job NamesXDB Attachments

When deleting Job Names, note that MSC.Patran will delete not only the database job name, but also any associated files outside of MSC.Patran that may have been created by that Job Name

When deleting XDB attachments, all results shown in the database from that XDB file will be detached/deleted

You can delete multiple XDB files at one time using the Yes for All option when asked to confirm this operation

Analysis: Read Input FileAnalysis: Read Input File

This function is IDENTICAL to that in File/Import (Function actually originated in Analysis menu)

Object & Method are not changeable

Entity Selection allows you to filter what is imported into MSC.Patran from a MSC.Nastran input deck

Can define offsets before importing to prevent ID conflicts

Auto-offset on by defaultTo have no offset, click on column or

cells targeted and either input 0 or NoneMake sure to hit return in input box!!

Analysis: Importing ResultsAnalysis: Importing Results Read Output2 & Attach XDB Both functions have 3 choices:Results Entities: Import/Attach only the

Results portion of the fileModel Only: Import only the skeleton

portion of the model (enough of the FE model so results could be displayed on the entities)Both: Import/Attach Results & Import

skeleton portion of the modelModel Only Characteristics:OP2: Imports Grids, Element Topology, &

Coordinate FramesXDB: Imports Grids, Element Topology,

Coordinate Frames, & Superelement Group Information

Analysis: Importing ResultsAnalysis: Importing Results

Attach XDB requires that the file be seen on the system. It can be either local or NFS mounted to the machine

No limit to the number of XDB files that can be attached to a MSC.Patran database or to the number of users attaching to a single XDB file

If an XDB file gets changed (contents or time/date stamp) or gets moved, and it is attached to a MSC.Patran database, you will need to delete the attachment & re-attach

Analysis: Importing ResultsAnalysis: Importing ResultsTranslation ParametersFrequently ignored by many MSC.Patran

usersNot a good thing!Instruct translator on what additional

types of Results Quantities to import (rotational nodal results, stress/strain invariants, etc.)

manipulate the data

Analysis: Importing ResultsAnalysis: Importing ResultsFor SOL200 jobs, XDB form will contain

Design Cycles to select. OP2 will import all Design CyclesFor Superelement jobs, XDB form will

allow you to select which SE to import (default is to import all SEs)XDB-Both form will optionally create

groups based on Models PIDXDB Import does not support P-Elements

Analysis: Importing ResultsAnalysis: Importing Results

OP2 Import physically imports & stores results in the MSC.Patran database. Dont need OP2 file after import

XDB imports & stores only metadata (result case names, XDB location) in MSC.Patran database. After attaching, you need to keep the XDB in the file system

XDB attached results can be accessed more quickly from MSC.Patran than OP2 imported results

OP2 Results Import no longer being enhanced in MSC.Patran (only bug fixes & general maintenance)

MSC.Patran Results ApplicationMSC.Patran Results Application

Manages the Display, Output, Transformation, Animation & Calculation of Result QuantitiesApplication based on Tools

(Fringe, Deformation, etc.)Soon to be the Single Source

Post-Processing tool for all of MSC.Patran (elimination of Insight)


There are 4 Actions to the Results Form, each of which has its own Objects:Create: Quick Plot, Deformation,

Fringe, Marker, Graph, Animation, Report, Results, FreebodyModify: Deformation, Fringe, Marker,

Graph, ReportPost: Plots, RangesDelete: Plots, Result Cases, Result Data


Results Forms designed such that for any of the Objects being created, all you need to do, at minimum, to create a Result Object/Tool is to Select:ObjectResult CaseResult TypePosition (when applicable)Quantity (when applicable)Whether to Animate the Tool upon creationApply

The other 3-4 Form Icons may be used to customize the Object/Tool at any stage of its creation, but are NOT necessary for the Object/Tool creation

Results: Quick PlotResults: Quick Plot A combined, yet simplified, version of the

Deformation & Fringe Tools Designed so that a minimum of 4 clicks

would be needed to create a combined Deformation/Fringe plot

Result QuantitiesFor Vector Type Results:Magnitude, X-Component, Y-Component, Z-

Component are AvailableFor Tensor Type Results:Many values shown which were not computed

by the Analysis codeMSC.Patran knows how to take Tensorial

Data and calculate Result Quantities that are not generated by the Analysis CodeMSC.Patran On-Line help describes the

computed Quantity Derivations in great detail (Part 7, Section 12.3)

One or more positions may be selectedFor Other Result Tools, if multiple Result

Cases are selected, only 1 position may be selected

Results: Quick PlotResults: Quick PlotPosition Sub Form (cont)Options Maximum: Plot the Maximum value for each element from either the

multiple result positions selected, or from multiple result cases at a singular result position

Minimum: Plot the Minimum value for each element from either the multiple result positions selected, or from multiple result cases at a singular result position

Average: Plot the Average value at each element from either the multiple result positions selected, or from multiple result cases at a singular result position

Sum: Plot the Sum value at each element from either the multiple result positions selected, or from multiple result cases at a singular result position

Merge: This option will Plot the first existing value encountered from any particular layer or Result Case. For instance if both top and bottom stresses are selected then only the top will be reported. This is useful for layers that are associated with certain element types. That way a layer with shells, a layer with solid, and a layer with beam elements can all be displayed simultaneously on the graphics screen in one operation.

Example of Fringe Results Filtering

Results: FringeResults: FringeResults AveragingMany Mistakes are made by not

knowing the defaults of these 3 Results Averaging values and what they doSome of the Options shown for

Domain/Method/Extrapolation are designed for Gauss Point ResultsMSC.Nastran uses Gauss Point

Locations to INTERNALLY calculate values, but they are not allowed to be output to the .F06/.OP2/.XDB

Lets talk about how the options operate, and how to use them to get correct correlation with the MSC.Nastran .F06 file

Results: FringeResults: Fringe Averaging Definition: DomainAll Entities: Average Nodal Values among ALL elements,

posted or not postedMaterial: Only Average Nodal Values common with

Elements that have the same Material PropertyProperty: Only Average Nodal Values common with

Elements that have the same Property setsTarget Entities: Average Nodal Values among Elements

defined in the Target Entities portion of the Fringe Form (2nd Icon)Element Type: Only Average Nodal Values common

among elements of the same type (Quad4, Tri3, etc.)None: No averaging performed at all


Averaging Definition: MethodDerive/Average: When computing Invariants, such as

from a Stress Tensor, compute the Invariant first, then Average the Invariants coming from each Element contribution at a common NodeAverage/Derive: Compute the Average of the Element-

Nodal components used in an Invariant calculation, and then use the Averaged values to Derive the InvariantDifference: At a node, the Maximum & Minimum

Element-Nodal value is determined, the difference computed and displayed. Sometimes called a Stress Jump Plot when plotting Stresses. Quality check methodSum: Sum all the Element-Nodal values common to a

Node and plot that Sum

Results: FringeResults: FringeAveraging Definition: ExtrapolationThis has more meaning for Analysis codes that

output Gauss Point ResultsDefinitions for MSC.Nastran Results are a bit

different and will be discussed hereShape Function: If Elemental Nodal values exist, use the values at

the NodesAverage: If Elemental Nodal Results exist, Average the values

within an element and assign that value to each Node in the elementCentroid: If Centroidal values exist, use the value at the CentroidMin: Review all the Result Values within an Element, find the

Minimum value, and assign that value to all Result locations within that ElementMax: Review all the Result Values within an Element, find the

Maximum value, and assign that value to all Result locations within that Element

Results: FringeResults: FringeExtrapolation Exceptions:MSC.Nastran has options to output results at Centroid

Only, or at both Nodes & CentroidIf Centroid only exists, some exceptions to the

Extrapolation MethodsShape Function: Take the Centroidal Value and assign it to each

Node within that ElementAverage: Since only a Centroidal Value exists, use that value as the

Average within the Element & assign to all NodesCentroid: No change, use the Centroidal ValueMin: The Minimum value is the Centroidal Value and is assigned to

each Node within the ElementMax: The Maximum value is the Centroidal Value and is assigned to

each Node within the Element

It needs to be re-emphasized that it is CRITICAL, when importing results, to use the BOTH option for Element Results Position

Results: FringeResults: FringeSo, How Do I Get MSC.Patran to Display

Correctly The Values in My .F06 File?Two Situations:Centroidal ResultsDisplay Attributes: Element Fill (Optionally, Shrink Fringe 100%

& Show Fringe Values)Plot Options: Domain=None, Extrapolation=Centroid

Nodal ResultsDisplay Attributes: Discrete/Smooth (Optionally, Shrink Fringe

100% & Show Fringe Values)Plot Options: Domain=None, Extrapolation=Shape Fn.

Note: If comparing Invariants (Von Mises, etc.), based from theTensor, unless you define an Averaging Domain, the Methods Derive/Average & Average/Derive will produce the same value

It is Strongly Suggested for Correlation w/ MSC.Nastran .F06 Results, to use Tensor Results w/ Marker-Tensor & Vector Results w/ Marker-Vector. For Cross-plotting (Tensor Results using Marker-Vector), Consult MSC.Patran Help, Part 7, Chapter 12.

Caution: Common misuse of ADC is to display Element Nodal results at Nodes (i.e., Grid Point Forces). This is incorrect. MSC.Patran currently does not have the ability to display this quantity. The best that MSC.Patran can do in this situation is to take the Element-Nodal data around a common Node, Average it, and display one value at the node. This is incorrect. Therefore, use Elements as ADC option, and compare to Element Centroidal Results.

MSC.Nastran) Fx, Fy, Fxy in MSC.Patran correspond directly to the MSC.Nastran convention. Transverse shear forces are shown as Qx and Qy in the .F06 file. MSC.Nastrans

Linear Statics guide shows these as Vx and Vy on the element. MSC.Patran shows these as Fyz = Vy = Qy and Fzx = Vx = Qx. The reason they are shown like this is because Fyz is really like Fzy, which in elasticity terms is the force in the Z direction, acting on the Y face. Fzx is the force in the Z direction acting on the X face of the element.

Moments are trickier. Mxx is supposed to be the moment acting on the X face of the element. MSC.Patran shows this as a vector in the X direction, giving you the initial impression that it is a torsional moment acting on that face. That is not true. If it is pointing in the positive X direction, then the moment is positive along the X face of bending, and the MSC.Nastran can be used for that direction. The same thing would be done for Myy.

For Mxy, this is a torsional moment on either the X or Y face of the shell. However, you see it as a in plane shear force on the element. MSC.Patran sees this as a XY quantity and displays it as such. Same conventions apply for the positive and negative directions. Don't confuse this for a moment acting along the x or y face.

The same holds true for displays in alternate CID's.

Spectrum And RangesSpectrum And Ranges

Spectrums & Ranges are used in fringe plotsAlso used in some marker plotsPatran allows you to customize the type of

Spectrums & Ranges that can be used for these types of plotsSpectrums & Ranges are saved to the

Patran database (Great candidate for things to add to a template database!!!)How can you do this effectively?

Spectrum & Range ControlSpectrum & Range Control

There are several locations in Patran where one can access Spectrums & Ranges

Spectrums: How toSpectrums: How to

The Spectrum form is broken up into 3 regionsCurrent/posted SpectrumCreate/Rename/Delete SpectrumSpectrum Attributes (this is what the

apply button is used for!!!)After posting a Spectrum, you

must re-apply the function that uses it (i.e., Results-Create/Fringe) or it will not display in the Viewport

Spectrum AdviceSpectrum Advice

Maximum number of color regions is 16 The color above the upper range value is reserved

for no-data (no data available to plot on the entities displayed)

A 15 color spectrum is great when you may reverse the background color, whereas a 16 color spectrum can cause confusion

There are 4 predefined 12 & 16 color spectrums called coldhotxx & hotcoldxx that define red to blue and blue to red spectrums (xx = 12 or 16)

Spectrum ExamplesSpectrum Examples

15 Color Spectrums that use either black or white for no-data change appropriately with background color reversals

16 Color Spectrums that use both black and white change appropriately with background color reversals and can be confusing

Example of HotCold12 Spectrum

Reversing Background ColorReversing Background Color

Common thing to do in Patran is to reverse the Viewport color from Black to WhiteDone via Display/Color PaletteClick on Black color brick and

change lightness from 0.00 to 1.00Click on White color brick and

change lightness from 1.00 to 0.00Hit apply

Reversing Background ColorReversing Background Color

There is a shareware utility function that will allow you to do this in 1 step via an icon

Modify your p3toolbar.def file with the following lines (NT version shown)

*ICON = bv_color_bw_reverse.bmp *CLASS = bv_color_bw_reverse *FUNCTION = toolbar *HELP = Reverse Black/White *LOAD ITEM
