Siemens Simcenter FEMAP 2306.0
Top new features in 2306
Rotor Dynamics (SOL 414) – New for version 2306!
Added support for Rotor Dynamics for Nastran solvers (SOL 414). The Rotor Dynamics SOL 414 has 5 new analysis types:
– SOL 414, 101 – Maneuvers a linear static analysis with rotational forces.
– SOL 414,103 – an Eigenvalue analysis that computes modes of the system at rest.
– SOL 414, 110 – a Complex Modal analysis for finding critical speeds and analyzing stability of the rotating system.
– SOL 414, 111 – a Harmonic analysis for frequency dependent excitation.
– SOL 414, 129 – Transient analysis.
Gear/Bearing/Fourier Elements and Element Property Types – New for version 2306!
To support Rotor Dynamics (SOL 414), new Element and Element Property types are added. The Gear element is used for connecting rotors. This property is written out to the GEAR card. The new Fourier element couples a node on the 3D portion of the model to a target node on the 2D Fourier axisymmetric portion of the model. The Fourier property maps to the FOU3 card. Finally, the new Bearing element supports the Nastran PBEAR2 property type. You can define Bearings with constant stiffness/mass/damping matrices, or stiffness/mass/damping matrix with rotation-speed/time/frequency dependent values.
Rotor Dynamics (SOL 414) Entities – New for version 2306!
In addition to the new properties, there are 3 new entity types available for Rotor Dynamics (SOL 414). The Model Info tree has a new Rotor Dynamics branch containing the 3 new entity types: XY Description Definitions, Bearing Speed, and Rotation Speed.
The XY Description Definition entity is used to create a Nastran OUTMGT entry which allows you to generate Nodal, Elemental, and/or Advanced XY Descriptions for various types of Rotor Dynamics analysis runs. These XY Descriptions appear as Femap functions which can be Descriptionted in the Charting Pane after Results are loaded.
The Bearing Speed entity maps to a Nastran SPEBE2 entry, and allows you to select the Rotors (or table) that Simcenter Nastran uses to retrieve the correct speed for Bearing elements. Bearing elements are dependent on Rotor speed.
The Rotational Speed entitiy is used to specify Rotation Speeds in 3 different forms: As Individual rotation speeds that writes to a Nastran OMEGA entry. As a Linear Sweep with equally spaced speeds that writes to a Nastran OMEGA1 entry. Finally, as a Logarithmic Sweep that writes to a Nastran OMEGA2 entry.
Rotor Dynamics Options and Rotor Assembly Selection – New for version 2306!
There is a new Nastran Rotor Dynamics Options dialog for the Rotor Dynamics solution parameters needed for the Nastran ROTORD entry. You can specify the Modeling of the Rotor Speed as either Constant, Linear, or a Function of a Sweeping Parameter (either Rotor Speed, Frequency and Time for SOL 414, 110 111 and 129 respectively).
Nastran ROTORD supports up to 10 Rotors which you enter in the new Rotor Modeling Assembly Selection dialog. These Rotor Speeds can have either a Constant Multiplier or a Multiplier defined by a Sweeping Parameter.
Rotor Dynamics Analysis Results – New for version 2306!
Results Data for Rotor Dynamics is stored to a file written in the HDF5 format, which is specific to Siemens products (the SCD5). For Femap version 2306, Femap is able to interact with the SCD5 file generated by SOL 414 to create both Output Sets & Vectors and Femap Functions for use in Postprocessing.
Geometry Interfaces
Updated Geometry Interfaces for importing different geometry formats from different CAD systems. Added support for CATIA V6, Inventor 2023, Rhino 7, and a new feGeometryInterface object for programmatic access to the capabilities of the File → Import → Geometry and File → Export →
Geometry commands.
All geometry interfaces have been updated with a common Read Options dialog. The new Read Options dialog offers appropriate options for supported geometry applications. Also, the new dialog continues to support Read Options from previous versions of Femap via the Alternative Interface… button.
ABAQUS Enhancement for Connections
Enhanced support for ABAQUS in order to export Connections. Specifically, or exporting and importing *CONTACT PAIR, *TIE, *SHELL TO SOLID COUPLING keywords.
Two new options, Adjust and Position Tolderance are added to the Define Connection Property dialog on the ABAQUS tab. They are located in the Other parameters section.
You can now toggle between on/off the Adjust parameter and set it to Yes or No. This option is activated if Connect Type is 0..Contact (i.e. *CONTACT PAIR). It is also activated when Connect Type is 1..Glued, and Enable Shell to Solid Coupling is turned off (i.e. *TIE). All options in the Other section are turned off when Connect Type is 1..Glued and Enable Shell to Solid Coupling is turned on.
In the case where Connect Type is 0..Contact (i.e. *CONTACT PAIR), the Position Tolerance option is activated only if Adjust is set to Yes or No. If Connect Type is 1..Glued and Enable Shell to Solid Coupling is turned off, you can turn on Adjust and Position Tolerance independently of each other. Export Abaqus input files with *TIE keyword along with *CONTACT PAIR, TIED, and import the Abaqus *SHELL TO SOLID COUPLING keyword. It is important to ensure the first surface in the data line is an edge-based surface name and the second surface is an element based solid surface name.
Teamcenter Integration
A new option, available in the Sign In To Teamcenter dialog, allows you to specify multiple Teamcenter server environments via the Edit Teamcenter Server Environments dialog. Add, remove and reorder Server Environments using the controls in the dialog.
Body Loads
Added support for Simcenter Nastran applied force direction from a Rotational Acceleration Body load. Added options when defining the Body Load to control which direction you want. A rotational acceleration setting, Direction of Applied Force is available in the Create Body Loads dialog (Model → Load → Body…). This setting has two options: Same as Acceleration and Opposite to Acceleration.
Multi Step Analysis Options
Updated control options for both Multi-Step Nonlinear Kinematic Analysis and Multi-Step Structural Analysis. The Multi-Step Global Control Options dialog box is replaced with the Strategy Parameters (NLCNTLG) dialog box, and the Multi-Step Control Options dialog box is replaced with the Strategy Parameters (NLCNTL2) dialog box.
API
New and updated API Objects and Attributes
– Added a new feGeometryInterface object to the API commands. It provides programmatic access to the capabilities of the File → Import → Geometry and File → Export → Geometry commands.
– Added NasMsNLKGlobalKINI, NasMsNLKGlobalFHMETH, fhpost, NasBulkFHPOSTVal, NasBulkFHPNST, NasBulkFHPNSTVal, NasBulkDFREQ, NasBulkDFREQVal, NasBulkRDMTRAK, NasBulkRDMTRAKVal, NasAppSpecUseRelativeMethod, NasAppSpecCID, NasAppSpecDir, vNasRotorRegionSelection, NasRotorRegionSelection, vNasRotorSpeedMultiplier, NasRotorSpeedMultiplier, vNasRotorSpeedMultiplierFn, NasRotorSpeedMultiplierFn, NasMsnlkCnt2PRDR, NasMsnlkCnt2PRDE, NasMsnlkCnt2ISTO, NasMsnlkCnt2IRDY, NasMsnlkCnt2BALF, NasMsnlkCnt2IA4, NasMsnlkCnt2IA12, NasCaseFHAROn, NasCaseFHAR, NasCaseFHACOn, and NasCaseFHAC Properties to the AnalysisMgr Object to support Rotor Dynamics (SOL 414) analysis.
– Added PutOUTMGTSetID, GetOUTMGTSet, ClearOUTMGTSet, PutOUTMGTSet, PutOMEGASetID, GetOMEGASet, ClearOMEGASet, and PutOMEGASet Methods to the AnalysisMgr Object to support Rotor Dynamics (SOL 414) analysis.
– Updated the feProp and feElem objects with property values associated with the Rotor Dynamics (SOL 414) Gear and Bearing elements.
– Updated the API Window so that closing a macro with the "x" on the tab, the Close command or the Close All command initializes the new macro with the standard Femap startup macro.
– Enhanced the API Programming pane to automatically create the default Femap starting script in a new window anytime you close the initial windows. Previously a default script was created, however it did not automatically setup to connect to Femap.
– Updated the Data Surface object and added an AutoEvaluate( ) method that can be used in place of Evaluate( ) and does not require any arguments. Also, Evaluate( ) can now be called with the either or both of the geomID and eDataType arguments set to zero to use the values of those options stored in the Data Surface.
– Added support fort writing PBUSH properties to Nastran with all zero stiffnesses. Model can then be hand edited later to update stiffness, but will run as-is just like the element wasn't there. (ER#10755337)
Pre-Processing
– Enhanced modifying an RBE3 element. If editing the independent node list, the standard entity select will propagate with already selected nodes if they have the same weight and DOFs selected.
Meshing
– Updated the Mesh → Between and Mesh → Region commands to automatically delete the extra mid-face nodes that were previously created but were not referenced by any element.
– Updated the Mesh → Region command to allow area selection of nodes in the starting/ending regions. Previously, nodes had to be picked in a "path" order so area selection was not normally feasible. The new capability only works if all selected nodes are along one continuous path of element edges and only works for planar meshing (Tri/Quad), not solids.
– Updated the Mesh → Region command to automatically merge/connect the new region with the selected starting/ending region nodes. Previously, new duplicate nodes were created requiring a later merge.
Interfaces – Comma Separated
– Updated the detection code for reading comma-separated results files to better detect basic or extended table formats. If you attempted to create an extended format CSV file from Excel, extra commas were added to the lines which only have one field in the defined format (like the table type) and that caused the code to think it was the basic format.
