Ansys EM CAD Integration through Workbench
Ansys Electromagnetics CAD integration is a Workbench feature available for Ansys Electromagnetics 3D Products - HFSS, Maxwell, Q3D, Icepak, and Mechanical, as the Ansys Framework. The feature is available only through Workbench, and is not available via standalone Ansys Electromagnetics products.
Ansys CAD integration provides a bi-directional dynamic link through Workbench. This makes it possible to get updated geometry from CAD, modify CAD parameters in Ansys Electromagnetics products, and return an updated geometry. The feature is non-associative due to a need to reassign boundaries if a modified CAD model is used. The process creates a User Defined Model (UDM) for each geometry source.

The UDM format makes it possible to exchange parameters. Ansys online help contains further description of the UDM feature and function.
The parameters shown in the previous example all have a DS prefix. This is the default for the Workbench Tools>Options for Geometry Import. To import parameters with different prefixes or names, assign an appropriate prefix or clear the Filtering Prefixes and Suffixes field.
Ansys Electromagnetics CAD integration makes it possible to consume geometry from multiple upstream sources (any CAD or Ansys Electromagnetics product).
This feature supports direct interfaces with major CAD systems, including:
- Creo Parametric
- UG NX
- CATIA V5
- SOLIDWORKS
- Autodesk Inventor
- Ansys Design Modeler (DM)
- Ansys SpaceClaim Direct Modeler (SCDM)
The CAD software must be installed on the user machine (not required for solve nodes).
