SpaceClaim parts and properties in ANSYS

Workbench applications only support flat (single-level) assemblies. An ANSYS part is created for each SpaceClaim part, at any level in the assembly. This part contains bodies that are visible and match the user import filters set in ANSYS. The filters are Import Solid Closed Bodies, Import Surface Closed Bodies, and Import Line Closed Bodies.

In ANSYS Design Closed Modeler, multi-bodied parts are parts (components) that contain more than one body (solid, surface, or line body). For example, for two surface or two solids to share topology, they must be placed in a multi-bodied part.

ANSYS Mechanical allows a maximum of two assembly levels. You can have components inside components, but nothing deeper.

If you send a component with two or more bodies into ANSYS Mechanical, then it shows up as a part with multiple bodies in it (multi-bodied part).

If you send a component with two or more bodies into ANSYS Design Closed Modeler, then everything becomes flat.

When you send a SpaceClaim assembly to ANSYS mechanical, it also gets flattened to 2 levels.

SpaceClaim part and body names in ANSYS

In Simulation, the Geometry node represents the assembly, and nodes immediately beneath that represent parts. If a part has more than one body, then child nodes are shown for each body, but if there is only one body, no child nodes are shown. This is based on the number of bodies transferred, which is subject to visibility and filters.

For a multi-body part ANSYS Mechanical displays the part name on the part node and the body name on the body node, but for a single-body part ANSYS displays a combined name on the part node, in the form <Part name> (<body name>). For example, Wheel (Solid Closed ).

The image above shows an assembly in SpaceClaim on the left and the same assembly in ANSYS on the right. Component Closed 1 is displayed as a single-body part in ANSYS and component 3 is moved to the root level.

Component Closed instance names are not transferred.

Mass properties

ANSYS will calculate the volume, center of gravity, and moments of inertia of the part if these values are not supplied. SpaceClaim supplies the volume and allows ANSYS to calculate the center of gravity and moment of inertia.
