Siemens Simcenter FEMAP 2401.0

Manage Femap Licensing
- Licensing is updated in Femap version 2401 to seamlessly accommodate the use of different licensing types, giving you the ability to access them in Femap without interrupting Femap (on the fly). This is done with Femap's new Manage Femap Licensing dialog which is now the centralized location for configuring licensing for Femap. This dialog provides a series of License Types to select from, controls to specify the License Location information, and a Connect button to connect to the license. The Manage Femap Licensing dialog is accessed from the main menu at Help → Manage Licensing.
With Manage Femap Licensing, you no longer need to exit Femap and execute a batch file ( go_…bat) to switch or set a new licensing type. The Manage Femap Licensing dialog also allows you to view available features, set your licensing to new or old legacy methods, connect to licenses, and receive feedback on connection status (without the need to shut down and restart Femap).
- Added checks in Registry as well as .ini for license path
Model
- A new Layup Builder dockable pane is available using the new Tools → Layup Builder command. Layup Builder is used to interactively create a large number of Layups using an intuitive table control. Layup Builder presents a different workflow for creating layup entities than the existing Layup Manager. Where Layup Manager workflow typically allows you to create the layup, and apply the layup to a property referenced by a specific element selection set, Layup Builder allows you to build a list of plys and select elements, surfaces or groups where each individual ply lands on. Using the Layup Builder table list, Femap finds the plies applied to specific elements, and builds the corresponding Layups and properties on them to automatically update the finite element model.
- A new Add Plys to Mesh command is available that allows you to add a specific number of plies of certain material and thickness at a specified location across selected Layup elements. You can now modify those layups to have the additional unidirectional ply at the top without modifying the rest of the model. Running this command (Model → Laminates → Add Plys to Mesh…) opens the Add New Ply to Mesh dialog which contains the controls used to add plys. The outcome of using this dialog is the new elements have an updated property and corresponding layup with the newly added plys.
- Added to Abaqus Connections Write: Activating and deactivating connections in the step feature added.
- Added changes for Neutral file read to support new Femap version 2401 Abaqus features.
- Updated the Femap Neutral file converter to 2401.
- Added improvements to Abaqus Import of load sets and constraint sets.
- Added functionality for Load from Layups commend to load information from an existing layup into a Layup Builder Stack.
- Commented out code that greyed out the data table radio button (if the data table was closed) when using the List -> Output -> Force Balance command. Now, if the radio button is selected when the data table is closed, it automatically opens the data table and displays the information.
- Added 'analysis' keyword for 'analysis model' solve/import/export commands from toolbars.
- Added keywords for - Model > Output > Computed Vectors –> factor of safety, margin of safety (Solidworks simulate) –> derived results (HyperView) Model > Output > Process –> create envelope loadsteps (HyperView) –> output set.
- Added special code to process extremely small circular and circular tube cross sections that does not depend on the current Parasolid Scale Factor Analysis Set Manager
- ABAQUS Analysis Manager and *STEP Import: Femap version 2401 updates the ABAQUS analysis interface to support *STEP import functionality, and additional improvements in the Analysis Set Manager for the Abaqus solver.
The Analysis Set Manager for the ABAQUS solver user interface is enhanced so ABAQUS terminologies are used throughout. For instance, “Global Requests and Conditions” is changed to "Initial Step”, and “Cases” are changed to “Steps”. The tree structure for an ABAQUS analysis will appear considerably different from previous versions of Femap.
The Initial Step defines the permanent Boundary Conditions (zero boundary conditions). The Boundary Conditions dialog opening from the Initial Step has the following options activated: Constraints, Initial Conditions, Constraint Equations, Contact Sets, and Glue Sets. These are applicable at the beginning of the analysis, and will be applied throughout the analysis. The Cases node of the analysis set is changed to Step which is equivalent to the analysis step terminology used by ABAQUS. Constraints, Loads, and Connections can be defined in each analysis Step. The glue type connections referenced in the initial step cannot be deactivated and remain active through all the analysis steps.
The Boundary Conditions dialog is modified for the ABAQUS solver so only ABAQUS related options are activated. When the dialog opens from any of the analysis steps, only the following options are activated: Constraints, Loads, and Contact Sets. These are applicable for each Step of the analysis.
- Abaqus Analysis Manager and *STEP import: Initial Conditions, Constarints Equations, Constraints fields in the Boundary Conditions dialog filter the combo boxes to show only relevant loads and constraints for the Abaqus solver. changed the default contact set for new creation of analysis set.

Analysis Interfaces
- Sloshing Analysis: Femap version 2401 includes extended support for dynamic analysis with incompressible fluids. This type of analysis is typically used to simulate fluid filled tanks. The dynamic behavior of fluid filled tanks is different from the unwetted structure, due to the effect of the fluid on the structure. Previous versions of Femap included support for modeling the incompressible fluids as a virtual fluid mass using boundary element techniques (i.e. the “Virtual Fluid Mass” method). Femap version 2401 now includes support for modeling the incompressible fluid explicitly as a defined fluid mass with finite elements (i.e. the “Defined Fluid Mass” method). This capability allows you to compute the elastic modes of the containing structure while accounting for the Sloshing of a fluid free surface, which cannot be done with the current Virtual Fluid Mass method.
- Added for Abaqus *STEP Import:
- CompareConstraintSets function modified. It now takes two additional arguments to compare only constraints, only constraint equations or both.
- Added code to import Constraint Equations and Constraints correctly. Code refactored and reordered functions. Proper initializations of variables and null check for pointers. Added code to show error messages to the user if any during *STEP import.
- Modifications to Abaqus export of connections.
- Write "** Femap Constraint Set Equation: <constraint set title>" comment before writing *EQUATION if a separate constraint set is referred for Constraint Equations in the Initial field. If the constraint equation is referring "From Constraints Set" then don't write this comment, This comment is used during Import of abaqus input file to determine if a new constraint set has to be created or not.
- Write appropriate comments to the input file to support import of activated/deactivated status of connections.
- Code changes to support successful import of activated/deactivated status of connections.
- Importing Abaqus input file sets the correct title for the analysis set created.
- Improved import of connection sets.

Users can clearly see the active group being used to run analysis.
- Added Abaqus Import improvements for importing load sets and constraint sets.
- Resulting from fix PR 10871254: Removed function OGL_NodalConnectivity::OGL_IsAeroCriteriaVectorID and replaced calls with the new function CResults::IsAeroResultVector. This function checks to see if the output set is valiud for aero and if not, prevents aero being valid.

Corrections

Analysis Set Manager
- Fixed an issue where *MODEL CHANGE data lines did not write the correct surface names when Write Entity Titles as Set names is unchecked.
- Corrected an issue where the NLCNTL2 parameter TSCVSC was incorrectly written as "TSVSC" in Femap versions 2301 and 2306.
- Corrected an issue where a combo box was loading an incorrect string resource. Originally "Generalized Alpha", now "Modified Generalized Alpha".
- Corrected an issue in graying with Sol 414 specific parameters.
- Corrected the IT2K default in nas write.
- Corrected an issue where an analysis set restarts if a new analysis set is set to analyze and put in the queue (PR# 10883134).
- Corrected an issue where geometric bcs is not shown in the drop down of constraint sets of the Boundary Conditions dialog for Abaqus.
- Corrected an issue with filtering of constraint sets in the Boundary Conditions dialog box.
- Corrected an issue with an error message that should be a warning only. The correction changes the error message to a warning message. Warning message is only shown if the nonlinear analysis->Solution Type is set to Transient (PR# 10969396).
- Corrected an issue whith Abaqus import/export. If Write All Groups as Sets is turned off and only one load set exists, then export and import of an Abaqus file does not set the load set in the analysis step. The fix correctly sets the load set in the analysis step.
Analysis Interfaces
- Corrected an issue with complex convert for Mises, princiapls. Replaced GetVectorCompute with GetVectorComputeType and removed else block from DB::GetVectorCompute (PR# 10900912).
- Corrected an issue when there no analysis results by zeroing min and max values.
- Corrected an issue which could cause incorrect syntax on the GPFORCE case control command in Random Response analysis.
- Resulting from fix to PR 10871254: Removed function OGL_NodalConnectivity::OGL_IsAeroCriteriaVectorID and replaced calls with the new function CResults::IsAeroResultVector. This function checks to see if the output set is valiud for aero and if not, prevents aero being valid.
- Corrected an issue which could occur when attaching to the scd5, is the solution group was not the first group in the data source.
- Corrected an issue with Abaqus import performance: Reduced the calls to CFemapAnalysisMgr::Get and CFemapAnalysisMgr::Put to improve performance
- Corrected an issue in writing ABAQUS standard beam sections: I-Beam output has been updated to move the beam to its shear center. ABAQUS standard section beams do not have any additional "offset", the beam is between its node at the beam shear center. Also, a correction was made in trapezoidal beams where the top and bottom widths were reversed on output.
Licensing
- Corrected an issue with OEM licensing which could cause certain translator entitlements to be lost during program execution.
Model
- Corrected an issue when writing out Parasolid file with more than one body. Femap was creating a copy of each body, clearing the ID attributes, but then wrote out the original bodies with ID attributes. When importing Parasolid bodies with their Femap ID Attributes intact, ID duplication could happen. Updated code to correctly write out the bodies without their Femap ID attributes.
- Corrected an issue with the Model > Output > Complex Expansion command (PR# 10789657).
- Corrected an issue with the S being added to the parameter list for ProcessAllSolidsConnectionRegions but no others.

- Corrected an issue with with complex results when using the Model > Output > Process command (PR# 10878640).
Loads and Constraints
- Fixed a filtering issue of constraint equations, constraints, and initial conditions. The issue was if the constraints or load definitions are removed so that the loads and constraints do not have an associated definition, then such type of constraints or loads did not appear in the drop down.
- Corrected an issue with *DLOAD (pressure loads). (PR# 10850246)
- Corrected an issue when Constraints or Loads are set to modify and no constraint or load is selected for a particular step in Abaqus solver, Export and import of the input file does not set the constraints or loads to modify but to new.
Meshing
- Corrected an issue with the close button is not working in the Mesh Control -> Interactive command.
Geometry
- Corrected an issue with invalid return codes inside CGeomIF::Import() when importing geometry using alternate geometry interface. ATP IDs fixed - 5, 131 - 134 (Import of IGES file format) Known results for above ATP IDs are banchmarked against Femap 2021.2 version.
- Corrected an issue where CLOAD/DLOAD does not refer the correct NSET/ELSET (PR# 10934763).
- Corrected an issue with the Import of glued connetions with Surface to Surface turned on does work correctly. The surface to surface option is not turned on after import Fixed the above PR: Surface to Surface option is turned on for glued connection after import (PR# 10930324)
- Corrected an issue when writing out a Parasolid file with more than one body. Femap was creating a copy of each body, clearing the ID attributes, but then was writing out the originalbodies with ID attributes. When importing Parasolid bodies with their Femap ID Attributes intact, ID duplication could happen. Updated the code to correctly write out the bodies without their Femap ID attributes.
- Corrrected an issue with the Translate Surface command not working after undo operation (ME-349882).
Teamcenter Share
- Corrected an issue with internet interruption when working in Teamcenter Share. The issue will cause to Femap freeze. This fix is for the status bar appearing despite internet access not being there (ME-297900).

- Corrected an issue with using Keyboard shortcuts to navigate the menubar (Alt+D+…) when mouse cursor is located at the location of sub-popup menu (PR #10860875).
- Print the failed check-in/check-out messages in the message box, when those operations are failed (ME-372010).
- Corrected an issue with Femap was unable to maintain toolbar location in a multi-monitor setup. Toolbars located on different monitors were shifted to the monitor with cursor pointer on Femap restart (PR #10850005).
- Corrected an issue where searching help for the "Customize" command in Command Finder shows no results. Set Femap Commands Guide page as default home page if command has no help assigned (ME-364452).
Graphics and Performance Graphics
- Corrected an issue where blanked surfaces are drawn when drawing a group containing the parent solid.
- Corrected an issue with switching between output sets, deformation not updating correctly as it does not detect a change.
- Corrected an issue with surface backfaces not being controlled by the pView- >label[PL_ELEM_FILL] flag.
- Corrected an issue when the force/moment/double ended/headless options were added. Also removed confusion of headless having no suffix and therefore "looked like" force.
- Corrected an issue with the solid arrow double ended with end reversal for negative values not working in shaders.
- Corrected an issue with multiple node picks on a single dialog - eg element create and measure between nodes. In vector deformation mode, for the first node to pick, the deformation is off as it should be but the incremental plot call for marking, resets the deformation values and causes nodes to be deformed for the picker.
- Corrected an issue with deformation vector arrow sizes.
- Corrected an issue with casting warnings from the Visual Studio error window.
- Corrected an issue where selection by group is not showing in marking
- Cortrected an issue where paste IDs were not showing in marking.
- Corrected an issue with Add (All) Connected Elements so marking does not get lost when rotating.
- Corrected an issue when using Entity Selection dialog Delete button to remove an entry in the pick list. The pick markers on the model were not being updated. When using preview, the pick markers on the model were undisplayed. Fixed in New Picking. Also added "X" symbols to entities that are picked as exclude.
- Corrected an issue with deformed picking of nodes in OGL and PG (cauesd by FUGUE addition of nodes).
- Correctged an issue with labelling constraints on nodes with permanent constraints in some cases of group displays.
- Corrected an issue where free face was not evaluated correctly for OGL when controlling layer visibility from the Visibility (ctrl-Q) dialog.
- Corrected an issue with NULL to 0 for clarity to match change from pointer to INT32.
- Corrected an issue where Unified Architecture was not updating the image immediately when using the toolbar icons to control entity labels. Workaround was to do a ctrl-G after the toolbar icon.
- Corrected an issue with view visibility based on free edge, free face etc.
- Corrected an issue where nodes location was scaled due to non zero normal[3].
- Corrected an issue in OpenGL Intel on Intel hardware, where the clipping plane flag did not function correctly inside shader code. In shader code, we need to roll our own clipping, but Intel does some odd clipping on each individual label.
- Corrected an issue where Performance Graphics incorrectly uses aero criteria results for elements. Elements should never show aero criteria or contour results.
- Corrected an issue where graphics could abort due to the addrows dialog of the CTableCtrl object.
- Corrected an issue where pressing ctrl-A while tracelines were visible, makes the tracelines zero length. Workaround is to do a ctrl-G.
- Corrected an issue with scaling of flat line arrows when drawn in non shader paths.
- Corrected an issue where solids were not being drawn correctly after the solid layer was changed (PR# 10929556).
- Corrected an issue with draw mode parameters for lighting.
- Corrected an issue where resutls are damaged by thumbnail drawing in PG/FUGUE shader code and VBO code - anything where data is stored on the GPU.
- Corrected an issue where user could not pick elements in New Picking in OGL if Elements are off. Appeared to cause freeface issues but they were there before.
- Corrected an issue with zero min max values if there are no results. May not handle all cases.
- Corrected an issue in dev where PG would not draw cpontour/criteria on freeface on shells due to incorrect change to freeface flags.
- Corrected an issue with surface backfaces not being controlled by pView->label[PL_ELEM_FILL] flag.
- Corrected an issue with selection by group not showing in marking.
- Corrected an issue with paste IDs not showing in marking.
- Corrected an issue with Add (All) Connected Elements so marking does not get lost when rotating.
- Corrected an issue with complex animation - was actually PG and OGL that were wrong.
- Corrected an issue where modifying the layer of a solid was not causing the graphics to regenerate.
- Corrected issues with geometry load scaling (non shader), and number of primitives emitted (shaders).
- Corrected an issue where errors have occured message when reading in a neutral file with no graphics window open. The model create that occurs before the file is read is then included in the command processing of error_has_been_called and logs the graphics card OEM and character set red "errors".
- Corrected an issue that caused OpenGL debug messages to be output (wgl context not set) when updating geometry (elements on curve for example) that triggered FUGUE_ReloadGeometryEntities.
