FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry
is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.
Manage all of the IDs for the entities that you create, and define ID ranges for all of the entities in each Include
file in relation to the full model in order to avoid ID duplication.
Perform automatic checks on CAD models, and identify potential issues with geometry that may slow down the meshing
process using the Verification and Comparison tools.
Properties define various physical and mathematical characteristics of parts such as sheet metal, extruded, and simplified
representations of parts. The assignment and unassignment of properties have a specific set of rules based on the
solver interface being used.
Materials definitions like properties quantitatively define physical characteristics. Many definitions exist like
isotropic, anisotropic, and orthotropic and other material laws that represent steel, plastics, composites, etc. The
assignment and unassignment of materials have a specific set of rules based on the solver interface being used.
Systems are available for assignment to properly control the orientation of entities like loads, transformations of
parts, model has degrees of freedom for movement during simulation among many other applications.
Use the Auto Contacts tool to determine contact interfaces between selections of components or elements. Based on
the user-specified options like proximity tolerance, surface creation method, main surface type, and secondary type,
the tool generates contacts based on set segments or node and element combinations.

Solver interfaces allowing for the indirect (components) and direct (elements)
assignment:
OptiStruct
Nastran
Abaqus
Samcef
EXODUS
Note: If a property is directly assigned to an element, that property takes
priority over any indirect property assigned to the component that the element
may be contained within.
Solver interfaces allowing for only indirect (component) assignment:
LS-DYNA
Radioss
ANSYS
Permas
Marc
Feko
From the Model ribbon, Properties tool group, click the
Assign Properties tool.
Optional: On the guide bar, click to enable selection filtering.
Assign or unassign properties.
Option
Description
Assign
Select a property to assign using the first selector.
Using the second selector, select the components or elements to
be assigned the property.
Click one of the following:
– Assign the property and
remain in the tool
– Assign the property and
exit the tool
– Exit the tool without
assigning
Both selectors need to be populated to for the assign
action buttons to be active.
Unassign
Using the second selector, select components or elements that
have a property assigned to them.
Click one of the following:
– Unassign the property and
remain in the tool
– Unassign the property and
exit the tool
– Exit the tool without
unassigning
Only the second selector can be populated to perform an
unassignment.
