Introduction

FEMAP offers a wide variety of tools available for post-processing as well as automatic results-based tasks

This presentation provides an introduction to many of the tools available to the analyst

Functionality presented represents what is available as of FEMAP v11.3

Apr 2016



Results Location

Results files in FEMAP for many different analysis types may be either internalized or attached • Internalized results are stored completely within the model

• Attached results reference the output file from the model

Apr 2016



Results Location

Once results are either internalized or attached they’re treated exactly the same within the Model (no changes to workflow are required) FEMAP currently supports attached results for • NASTRAN XDB, OP2 • FEMAP FNO • Abaqus ODB • CSV

Result Type Pros Cons Internalized Results • Simple file management

• May be marginally faster with smaller result files

• Increased database size; can impact overall FEMAP performance

Attached Results • Greatly improved performance for large results files

• Greatly improved performance for transient results

• Multiple results files may be attached in a single operation

• When transmitting model, results file(s) must be transmitted with the model

Apr 2016



Results Location

Attach behavior for analyses that are launched from within FEMAP and automatically imported controlled via a preference that is off by default

Apr 2016



Results Location

The Results File Manager, under File->Attach to Results provides an interface to manager results files that have been attached • When opening a model which

has missing results, FEMAP will display a warning message, then present options for locating the results and reattaching

• Results files are compared via a checksum to determine if the results in the attached results file are identical to the results when the file was originally attached. If a discrepancy is found, a warning is issued

Contour Plots Displaying Multiple Contour Vectors

Line element results can be displayed with other element types in a contour plot • Multiple Contour Vectors option displays solid, shell and line element results in

the same contour plot (or multiple line elements types: Bar, Beam, Bush, etc)

Apr 2016



Contour Plots Setting Threshold Value(s)

A Max Threshold or Max/Min Threshold can now be set for contour plots using the Level Mode of the Contour/Criteria Levels view option • Contour Fill Mode must be set to Level Colors Example: Max Threshold Value = 4000, Min Threshold Value = 750

Post Toolbox Overview Freebody Toolbox

The Freebody Toolbox is used to create and display freebodies. Freebodies created in the Freebody Toolbox can be selected for display in any view

• Global Settings – These controls affect all freebodies in the model. Control global display of freebodies, select output set (tied to contour and deform) and enable data summation on nodes

• Freebody Properties – These controls are related to individual freebodies, such as selecting nodes and elements

• View Properties – These are global settings that affect freebody visualization (symbol sizes, vector scaling, etc). Same as found in View Options (F6)

Apr 2016



Creating a New Freebody • In the Freebody Toolbox, new Freebody Displays are created within the

Freebody Manager

• The New Freebody dialog allows for setup of basic settings, such as freebody

display mode, vector display, and contribution selection • Any of the settings applied in the New Freebody dialog can be changed at any

time within the toolbox

Post Toolbox Overview Freebody Toolbox – Creating a Freebody

Apr 2016



FEMAP Freebody Display Modes – There are three methods of freebody display in FEMAP • Freebody – user selects the elements, FEMAP automatically selects related

nodes. Intended to display a balanced set of loads on a discrete piece of structure

• Interface Load – user selects both nodes and elements and FEMAP calculates a summation of loads and forces across the interface and displays as a single vector

• Section Cut – similar to interface load, a summed load across an interface is calculated and displayed, however node and element selection is automated by FEMAP. The user selects a “cutting plane”. The cutting plane can then be dynamically located within the model using different methods.

Post Toolbox Overview Freebody Toolbox – Results Validation

The Freebody Toolbox includes a tool for results validation that can be useful in debugging models and results. It can help warn about missing results

FREEBODY RESULTS VALIDATION SUMMARY

Freebody: 1..Sample Freebody Output Set: 1..NX NASTRAN Case 1

Selected Nodes: OK Selected Elements: OK

Applied Results: OK Reaction Results: OK Multi Point Reaction Results: OK Freebody Element Results: Not Requested Peripheral Element Results: OK Contact Results: Not Requested Glue Results: Not Requested Nodal Summation Results: Not Requested

Do selected nodes / elements exist in the model?

Do results for valid node / element pairs exist?

Does the output vector exist?

Does the output vector exist?

Apr 2016



Post Toolbox Overview Freebody Toolbox – Results Validation

When potential discrepancies have been found in the model / selected results, the icon changes to a warning:

FREEBODY RESULTS VALIDATION SUMMARY

Freebody: 1..Untitled Output Set: 2..NX NASTRAN Case 1

Selected Nodes: OK Selected Elements: OK

Applied Results: OK (Alternate vectors used) Reaction Results: OK (Alternate vectors used) Multi Point Reaction Results: OK Freebody Element Results: Not Requested Peripheral Element Results: Missing Results Contact Results: Not Requested Glue Results: OK Nodal Summation Results: Not Requested

“Alternate vectors” indicates results were not obtained with GPFO request. Usually okay,

but may indicate an issue if unexpected.

Use of alternate vectors does

not cause a warning flag in the validation icon

When elemental results have an error, this indicates that

results for the node / element pair do not exist in the results.

This data can optionally be

listed with discrepant node/element pairs

Apr 2016



Output Transformation

Transformation of results can be done on-the-fly for use within views and certain listing options, or the results can be calculated and stored as new output vectors • Output can be transformed on-the-fly for deformed and contour plots • Output can also be transformed and stored within the model

Plate membrane forces with element orientation Plate membrane forces transformed to global rectangular CS

Apr 2016



Output Transformation Deformed Results Transformations

Deformed results can be transformed into any model coordinate system or the nodal output coordinate system • Selected components of the

deformation in the global coordinate system can be selected for transformation

• When displaying deformations of total (resultant) vectors, display of individual components can be toggled on and off

Deformation transformations are done on-the-fly for visualization and do not affect the data stored in the model

Apr 2016



Output Transformation Contoured Results Transformations

Contoured results for nodal output, plate output and solid output can be transformed into a variety of orientations

• Nodal • Model Coordinate System • Nodal Output CS

• Plate • Material Direction (must be defined) • Into CS

• When transforming into a coordinate system the selected axis represents where the X vector will be transformed to

• Results should be selected in accordance to this • Along a Vector

• Solid • Model CS • Material Direction (must be defined)

Contour transformation options are valid for all contour styles, except Beam Diagram and do not affect the data stored in the model

Apr 2016



Output Transformation Elemental Results Orientation

For elemental results to be properly displayed or transformed, the results orientation needs to be properly set • Normally this shouldn’t be changed unless the solver output is oriented

differently than expected

Apr 2016



Output Transformation Model->Output->Transform

In addition to transforming results for deformed and contour display, the Model->Output->Transform command can be used to transform data and store it within the model itself • This can be useful for listing • Avoids calculation in the future • Stored as “User Vectors” in the

9,000,000 ID range

Apr 2016



Working with Complex Output Complex Results Options

• On-the-fly postprocessing of complex data by specifying a Static Display Phase Angle and/or Animation Phase Increment to see actual results

• Model Settings – Options used for entire model • View Override – Options used for Active View only

Apr 2016



Working with Complex Output Static Display Phase Angle

• Specify Static Display Phase Angle to display “Total” vectors (i.e., Total Translation) using both Magnitude and specified Phase Angle

• Principal Stresses and Mean Stress will be calculated “on-the-fly” for display • Static Display Phase Angle appears in Post Titles for reference

Results Ranking

The List->Output->Results Ranking to Data Table command can be used to envelope results across output sets • Returns extreme output sets for

selected entities/ materials/properties, or extreme entities/properties/materials for selected output sets

• Vectors can be ranked individually or all vectors can be treated as a single quantity

• Results quantities can be ranked on max value, min value or max absolute, for any number of “top” cases

• Works on both internalized and attached output

Apr 2016



Results Ranking

Example: Find the 5 maximum result cases for plate membrane forces across all elements in the model

Results Ranking Output to FNO

When using the Results Ranking tool to find worst-case entities or output sets on a global-level FEM, the PostProcessing->GROUP_POST_FNO Custom Tool can be used to export a portion of the results for local analysis • Select a group containing entities for output • Select output set(s) and vector(s) for export • FEMAP will export a neutral file containing the only the selected entities and

output quantities When exporting results for grid point forces, it’s important to select all the GPFO output vectors (85000 range) as well as ensuring that the group for export contains the elements of interest as well as those connected to the elements of interest. Failure to do so could potentially result in unbalanced freebodies.

Apr 2016



Charting

The Charting Pane provides a simple interface for creating plots of output data as well as function data without relying on an external program, such as Excel • Tools->Charting • Separate pane, like the API

Programming Window or Data Table • Create Data Series within the

Charting Pane that serve as source data for the charts

• Create individual Charts to display Data Series with individual styles

• Charts and Chart Data Series are stored in the database and persist across FEMAP sessions

• Charts automatically update if output changes

Apr 2016



Charting Chart Data Series

Chart Data Series are “data sources” that are used to retrieve output or function data from the model for display in individual charts • Multiple types available

• vs. Entity • vs. Output Set • Vector vs. Vector • Function

• Data is retrieved from the model real-time – if the results or function data is updated, this is automatically reflected in the plot without user interaction

• By default, Chart Data Series that are created are automatically added to the active Chart

Apr 2016



Charting Charts

Once a Chart Data Series has been created, it can be displayed in a Chart

• Any number of charts can be created in a model

• Several different styles exist • Scatter plot • Line • Step • Area

• Control over • Colors • Axis labeling • Title • Fonts • Markers • Labels

Analysis Studies

Analysis Studies allow the organization of Results Sets into “groups” of results sets • Manually create or automatically created at

the successful completion of an analysis • Default behavior is to create a new

study for each analysis • This can be modified in

Preferences->Results • All Result Sets are always shown in the

All Results leaf, regardless of their inclusion into an Analysis Study

• A result set may reside within only a single Analysis Study at one time

Apr 2016



Analysis Studies Naming Conventions

Various naming convention options exist for Analysis Studies and can be set in Preferences->Results

• Default – Nastran title (if available) for OP2 and XDB, otherwise file name

• Analysis Set Title – Use the Analysis Set title for jobs launched from FEMAP. When importing results manually, the active Analysis Set is used – this may not correspond to the actual Analysis Set

• File Name – Use the file name of the output file

• Nastran Title – Use the Nastran title, for OP2 or XDB. Otherwise, “Analysis Study” is the default title

Apr 2016



Analysis Studies Naming Conventions – Output Sets

Similar to Analysis Studies, options exist for naming of Nastran Output Sets as well

• Standard – Solver, subcase and value (when applicable)

• TITLE • SUBTITLE • LABEL • SUBTITLE,LABEL

• Use the “Append Femap Title” option to

append the output set value to any of the options other than “Standard”. This can be useful for output sets with an associated value, such as modal runs, non-linear, and eigenvalue runs

Apr 2016



Analysis Studies Naming Conventions – Static Subcase IDs

When the “Use Static Subcase IDs” option is enabled in Preferences, the output set ID will correspond to the NASTRAN Static Subcase ID

Apr 2016



Analysis Studies Revision Tracking

When, “Track Revision” is enabled, subsequent runs of the same Analysis Set or importing a single file again will result in a revision number being appended

Because duplicate IDs may not be used with output sets, if this option is used in conjunction with “Use Static Subcase ID,” the Output Set ID is incremented from the subcase ID with the revision number

Loads from Output From Freebody

The Model->Load->From Freebody command will create loads from freebodies that exist in the model. This command is intended to be used when creating loads in the same model as the results • Select one or more freebodies • Select one or more output set(s)

• Loads can be created as a new

definition in an existing set (only when single output set is selected), or in a new load set

• Optionally create loads for nodal summations or interface load

• Creating a load for the interface load will create a new node at the summation point

Loads from Output From Freebody… Multi-Model

When applying loads from a coarse-grid global model to a fine-grid detail model, the Multi-Model option in the Load->From Freebody command should be used • Start with a balanced freebody in a coarse

grid FEM • FEMAP can automatically locate suitable

target nodes in the fine grid FEM and will connect with RBE3 elements

• Once properly constrained, the detail FEM is ready to run with a mapped set of loads

Beam Calculator

The FEMAP Beam Calculator provides detail section stresses on a line element using beam forces recovered via a standard analysis - A local finite-element solution is

used to calculate section stresses - Any solver may be used as a

“source” for the forces used in the calculations

- Multiple stress calculations are available, including von Mises, max shear, max/min principal, axial, Y/Z shear and combined shear

- Requires line elements with a section

Apr 2016



Beam Calculator Basic Setup

View->Advanced Post->Beam Cross Section - Select Output Set - Select forces from Output Set to include in calculations

Vector IDs used for forces are dependent on element type (bar, beam, etc) as well as solver (Nastran, Abaqus, Ansys, etc) and are automatically selected by FEMAP

Beam Calculator Section Location

The section location (from end A to end B) can be modified using the slider, or manually specifying an option - By default, only a single section is displayed at the selected location

- Enabling multiple sections will perform calculations / display at end A, end B and the equally-spaced points in between (2 to 10)

- Default of 3 displays sections at end A, the midpoint and end B - Contour plots can be displayed either in screen space or model space

- When displaying in screen space, only a single section for a single element can be displayed

Beam Calculator Combined Shear Vector Plot

When displaying Combined Shear Stress quantities, the results may be viewed as a contour vector plot to visualize the direction of shear flow

The entity selector can be used to select nodes and elements based on results • This type of selection is available using the

standard selector any time nodes or elements are being selected, regardless of the intended operation

• Ex: change the property of shell elements by selecting those above a certain stress level

• Any number of output sets may be selected for filtering

Apr 2016




Multiple selection criteria may be set based on varying output conditions Keep in mind that the filtering is done at selection – groups created using these selection tools will not be updated if the output changes

API Results Browsing Object

The FEMAP API provides multiple ways for accessing results data, however generally the most efficient way is to use the Results Browsing Object Notionally, the Results Browsing Object is very similar to the FEMAP Data Table:

Apr 2016



API Results Browsing Object - Usage

The FEMAP Results Browsing Object is a read-only object. Its primary function is to access a “table” of data, however it can also replicate many of the output set / vector querying methods of the OutputSet and Output objects. Unlike the Output object, the Results Browsing Object allows for access to results from many different output sets and vectors via a single API call. Methods are grouped into three categories: - Setup & population - Results set / vector information - Results access / manipulation

Except in rare circumstances, the Results Browsing Object SHOULD NOT be used to access results one-at-a-time; performance may be poor.

Caution

!

In most cases, the Results Browsing Object can be used as a direct replacement for the OutputSet and Output objects
