HFSS15: UDM compared to User Defined Primitives

User Defined Models (UDM) resemble User Defined Primitives (UDP):

• ANSYS EM products can be extended by users through new UDMs

• UDM plugins are discovered by searching standard directory paths

• Plugins for static UDM can build model using ‘callback interfaces’ (like create-box, create-cylinder, subtract etc) similar to UDP

• UDMs run inside ANSYS EM applications

• UDMs provide geometry, topology, persistence and parameters

In contrast to UDP:

• UDM provides multiple Parts/CS/etc.

UDP provides primitive operation only for a single Part

• UDM provides part attributes and material assignment

UDP does not define part attributes or material

UDM Properties have four tabs – Definitions, Parameters, Options and Info

• Definition tab has:

UDM name

Coordinate system used to position UDM

May have external reference to file

• Info tab has:

UDM dll name, dll location, version etc

• Option tab:

may have options if any
