Winding Bodies & Tool
• Feature: Design Modeler (DM) includes two new tools to allow a user to easily create current carrying coils: – Winding Bodies: Used to represent wound coils for source excitation. The advantage of these bodies is that they are not 3D CAD objects, and hence simplify modeling/meshing of winding structures. – Upon “attach to Simulation”, Winding Bodies are assigned as Conductor bodies. – Winding Tool: Used to create more complex coils for motor windings. The Winding Tool uses a Worksheet table format to drive the creation of multiply connected Winding Bodies. Or a user can read in a text file created by MSExcel.
