User Defined Model (UDM)

A User Defined Model (UDM) is collection of externally defined parts imported into an Ansys EM 3D Modeler or created using a C or Python script.

• UDM includes part attributes (like name, color etc) and material assignment
• UDM can also have external coordinate systems and corresponding planes
• UDM parts can be parameterized and manipulated in Ansys EM modeler just like any other part

UDM can either represent Static geometry models or

• Dynamic links to models of external geometry editors

UDM uses same plugin technology as User Defined Part (UDP)
