New FEM and Simulation dialog box

File Names
Displays the names of the FEM and Simulation files created by the New FEM and Simulation command.
CAD Part
Associate to Master PartNote: This option does not appear in Design Simulation. Creates an association between the FEM and Simulation files and the selected master part.
Part Lists the current master part.
Idealized Part
Appears when the Associate to Master Part check box is selected.
Create Idealized Part Creates and associates an idealized part to the selected master part.All geometry idealization occurs on the idealized part; the master part is unchanged.
Name Displays the name of the idealized part file.
Bodies
Appears when the Associate to Master Part check box is selected.
Bodies to Use Specifies which bodies to include in the FEM and Simulation files when the master part contains multiple bodies.All VisibleIncludes all the currently visible solid or sheet bodies from the master part.Bodies that are not currently visible are not included.Note: The software does not remove a body from a FEM file if you later hide the body. If you later display additional bodies, the software automatically adds those to the FEM file.AllIncludes all solid or sheet bodies from the master part.Any new bodies that you create with idealized part commands (such as Midsurface or Partition) are automatically added to the FEM file.Note: Because lightweight facet bodies contain no polygon edge or face data, you cannot create a FEM on lightweight facet representations in assembly reference sets. If you select All, the software skips any lightweight facet bodies in the assembly part.SelectIncludes only the solid or sheet bodies that you select.Any new bodies that you create with idealized part commands are not automatically added to the FEM file. You must manually edit the FEM file to add any additional bodies.NoneCreates FEM and Simulation files that include no bodies from the master part.Note: These options have no effect on the idealized part file. That file always contains all the bodies from the master part.
Polygon Body Resolution Controls the level of tessellation that the software uses to create the polygon bodies.StandardCreates the polygon geometry using the standard level of tessellation. This option provides the best balance between accurately representing the data from the underlying part in the polygon geometry and minimizing the size of the FEM file.MediumCreates the polygon geometry using a higher level of tessellation to capture the curvature of edges very accurately.HighCreates the polygon geometry using the highest level of tessellation. This option is useful for parts in which you want to capture the curvature of edges and faces very accurately. With this option, the software highly refines the tessellation in the regions where edge and face curvature are high.For more information, see Controlling polygon body tessellation.
Select Bodies Appears when Bodies to Use is set to Select.Lets you select the bodes to add to the FEM and Simulation files.
Geometry
Appears when the Associate to Master Part check box is selected.
Geometry Options Opens the Geometry Options dialog box.You can specify any optional non-part geometry to include in the FEM polygon geometry representation of the part. You can include:PointsCoordinate SystemsLinesArcs/CirclesSplinesSketch CurvesBy default, all Geometry Options are set to Off.Note: If you select the Points check box, the software includes existing points from your CAD model in the new polygon geometry. However, even if the points were associated to your original CAD geometry, the software does not maintain that associativity in the polygon geometry.
Solver Environment
Solver Specifies the solver to use.
Analysis Type Specifies the type of analysis to perform.
2D Solid OptionNote: This option does not appear in Design Simulation. Appears when Solver is set to Simcenter Nastran, Simcenter 3D Multiphysics, ANSYS, Abaqus, or Ideas Unv.Specifies the plane on which you can create axisymmetric, plane strain, and plane stress elements.NoneNo 2D solid elements can be used.ZX Plane, Z AxisAppears when Solver is set to Simcenter Nastran or Simcenter 3D Multiphysics.If 2D solid elements are used, they must be on the ZX plane. The rotational axis is Z.XY Plane, X AxisAppears when Solver is set to Simcenter Nastran or Simcenter 3D Multiphysics.If 2D solid elements are used, they must be on the XY plane. The rotational axis is X.XY Plane, Y AxisAppears when Solver is set to ANSYS, Abaqus, or Ideas Unv.If 2D solid elements are used, they must be on the XY plane. The rotational axis is Y.
Mesh Morphing
Save Full Morphing DataNote: This option does not appear in Design Simulation. Controls whether the software stores comprehensive data about modifications to the underlying CAD geometry. If you plan to use morphing, rather than the FEM Update command, to update the meshes in your model in subsequent sessions, you should select this option. When you select the Save Full Morphing Data option, the software stores additional data about changes to the CAD geometry. If you use the morphing commands in a subsequent session, this additional data allows the software to produce higher quality morphing results.Note: The Save Full Morphing Data option does not have any impact on the quality of morphing results when you modify the CAE geometry and morph an associated mesh in the same session.
