Siemens Simcenter FEMAP 2301.1 (2301 MP1) Win x64

Updates and Enhancements

Interfaces - Simcenter Nastran
- Added support for the Subspace iteration eigenvalue extraction method in the NASTRAN Modal Analysis dialog box as support was added in Simcenter Nastran 2212. Previously, this option was not available to select because it was not supported.
Output and Postprocessing
- Added support for attaching to MSC Nastran NH5RDBs created using the 2019.0 Schema
- Added support for the NODAL_GRID_FORCE, ELEMENTAL_STRESS_GAP_NL, ELEMENTAL_STRESS_BEAM_NL, and ELEMENTAL_ENERGY_STRAIN_ELEM NH5RDB Datasets for MSC Nastran.

Corrections

Graphics - Overall
- Corrected issue when using Front Pick to select an element face which cased the face to remain highlighted in the graphics window when the mouse moved outside the model.
- Corrected issue where updated curves was not being drawn correctly. For instance, this could occur when using the Modify -> Scale -> Curve command (PR# 10616425).
Graphics - Unified Architecture
- Corrected issue when using the Project Curve operation in the Geometry Editing tool of the Meshing Toolbox, other operations in the Meshing Toolbox, and other commands throughout Femap which caused Femap to exit unexpectedly.
- Corrected issue where points were not pickable using the Geometry -> Curve - From Surface -> Split At Locations command if they were created using the Modify -> Break -> At Location command until the view was regenerated.
- Corrected issue where Snap to Point did not work for points created using the Geometry -> Point command (PR# 10600669).
- Corrected issue where geometry-based loads and boundary conditions were not hidden correctly with the corresponding geometry.
- Corrected issue where coordinate systems were not drawn in groups.
- Corrected issue where coordinate systems were not always being drawn shaded.
- Corrected issue where geometry-based loads with their Direction defined by Vector, Along Curve, Normal to Plane, or Normal to Surface in the various Create Loads dialog boxes were not being drawn correctly.
- Corrected issue where surfaces and curves could be selected when any number of groups was being displayed (i.e., not the Full Model) if they were part of a solid/volume in the group but not actually in the group themselves. In this situation, they should not have been pickable.
- Corrected issue where facets were not being drawn on the faceted surfaces of Convergent Bodies (i.e., surfaces defined by facets and not by NURBS)
- Corrected issue where individual surfaces in boundary surfaces, individual curves in combined curves, and individual points internal to boundary surfaces were not highlighted when attempting to select the appropriate entity type.
- Corrected issue which required the Window -> Regenerate command (Ctrl-G hotkey) to be used after toggling the Filled Edges option found on the View Style icon menu found on both the View and View - Simple Toolbars.
- Corrected issue which could occur when switching from View Visible Layers Only to View All Layers using the context-sensitive menu for Layers in the Model Info tree or switching from View Multiple Layers to View All Layers on the Layer tab of the View -> Visibility command which caused the view to not be updated as expected (PR# 10625668)
Geometry
- Corrected issue with splitting curves introduced in v2301. All commands and other functionality where curves were split at a point now function as they did in previous versions of Femap.

User Interface - Dockable Panes
Model Info tree
- Corrected issues impacting the Show/Hide Reverse, Show Selected Only, Show All, and Hide All commands on the context-sensitive menus for the Visibility check boxes available for multiple entity types in the Model Info tree. If the branch of the tree being updated contained more than the maximum number of displayed entities, thus is showing the Next/Prev options, these commands might cause the check boxes to show the wrong state of visibility for entities. In particular, Show/
Hide Reverse almost never worked as expected.
- Corrected issue that caused Load Definitions to disappear from the Model Info tree if Load Sets were renumbered. The Load Definitions were not deleted, they simply were no longer included in the tree. This problem only occurred in v2301 and could be rectified by reloading the tree from the model (PR# 10614667).
Analysis Monitor and Analysis Queue
- Corrected issue which caused the Elapsed Time field in the Analysis Monitor Pane to not update until the analysis completed (PR# 10598237).
- Corrected issue where the state of the INREL bulk data option was not accurately reflected in the tree structure of an Analysis Set within the Analysis Set Manager (PR# 10591068).
Interfaces - Femap Neutral
- Corrected issues which caused data for Element Monitor Points to be written incorrectly to the neutral file in all but very specific circumstances. Once the data was written incorrectly, which could occur using v2022.2 (up to MP 3) or v2301, the neutral file could not by imported correctly into any version of FEMAP which can read Element Monitor Point (MONPNT2) data from the neutral file, including v2022.2 MP 4 and v2301 MP 1. Even though v2022.2 MP 4 and v2301 MP 1 now write the Neutral file correctly, those files can only be imported properly into 2022.2 (MP 4 and above) and 2301 (MP 1 and above), as 2022.2 (MP 3 and below) and 2301 both also have an issue reading the properly formatted Neutral File.
Interfaces - Simcenter Nastran
- Corrected issue which would incorrectly write certain entries to input file when attempting to use the Subspace option in the NASTRAN Modal Analysis dialog box for a Model Frequency Response analysis (PR# 10621489).
Meshing
- Corrected issue which allowed creation of a Rigid element with no DOF specified when using the RBE2 tab in the Define RIGID Element dialog box.
- Corrected issue with Mesh->Bodies command that did not allow Mesh Points to be honored when the "All Geometry" option was selected in the Mesh Associativity section on the Geometry tab. This issue also impacted the mesh sizing around small holes and features and on surfaces with small radii of curvature.
Output and Postprocessing
- Corrected issue which could cause incorrect vectors to be indexed when attaching to a MSC Nastran NH5RDB with composites results and multiple domains (Output Sets)
- Corrected issue with post-processing where results for different domains (Output Sets) from an MSC Nastran NH5RDB were not collected correctly.
- Corrected issue which prevented the functionality of the "Merge" tab in the "Model -> Output -> Process" command from fully merging output when selected vectors had components.
- Corrected issue which could cause Femap to exit unexpectedly if an attached SCD5 file contained "SCBucklingMode" legend information.
- Corrected issue which caused contact forces, which Nastran already returns in the "Basic" coordinate system, to be transformed to "Basic" from the nodal output CSys, leading to incorrect results.
- Corrected issue when attaching to Nastran output files containing results for laminate elements created by a nonlinear analysis, where output vectors were only created for a subset of plys for some laminate elements (PR# 10521948).
Documentation and Help
- Corrected issue where the Analysis Program Interfaces section of the User Guide did not show the currently supported version for various solvers, which are 2021 for ABAQUS, 2021 R2 for ANSYS, 2021 R2 for LS-Dyna, and 2212 for Simcenter Nastran.
API
- Corrected issue with Info_Orient... calls which set options in the Current Output Orientation dialog box used to set the "From" orientation accessed by various commands to specify output transformation options in the current model. Also, corrected the same issue with the Pref_Orient... calls which set default values for output orientation for the various commands which transform output. In both cases, these properties were unable to be set to the value of 3 in previous versions.
