PEC |
For PEC materials, all interior electric fields are zero. In many cases, highly conductive metals such as silver, copper, aluminum, and iron, can be modeled as perfectly conducting.
In the case of coincident or overlapping materials, materials are assigned the following priority:

Click
Materials within the Definitions section under the EMA3D tab in the ribbon. Then select
PEC.

Use the appropriate selection tool (body
, surface
, or line
) to assign the PEC material. To assign material properties, either select the geometric entity in the model window or in the Structure Tree.

Click OK
to complete the definition.
Adjust the definitions of the PEC material at any time by right clicking it within the Simulation Tree and selecting Edit from the pop-up menu.
