Shared Topology in Ansys

SpaceClaim can share topology (face, edge, and vertex connections) between touching or intersecting bodies and surfaces in designs that are transferred to Ansys.

Shared topology is the only way to achieve a conformal mesh where bodies meet, and is the only way to be certain that the intersection of bodies is meshed perfectly.

Shared topology also applies to volume and surface bodies that are completely inside of other volume or surface bodies. This situation is common in analyses involving fluid flow.

The Shared Topology settings are:

  • None (default) does nothing to geometry during transfer to Ansys/Workbench

  • Merge is intended only for Baffles used in CFD analysis.

    This option merges surfaces that are fully embedded within a solid. Surface edges that lie on the solid are valid. Surfaces that intersect the solid are not valid and must be trimmed before executing Shared Topology.

  • Share imprints and merges all bodies in the components and transfers the result to ANSYS as a multi-body part

  • Group groups all bodies in a component into a multibody part, but does NOT merge or share faces and edges of the bodies with each other
