Faces (Geometry)

Faces are individual surfaces of a part. By default, a face is set to perfect electric conductor (PEC).

Note: The term “face” is used to differentiate from “surface”. A surface refers to a 2D primitive (for example, a polygon).
Selecting a face in the 3D view selects the corresponding face in the details tree. Conversely, selecting a face in the details tree selects the corresponding face in the 3D view.

Figure 1. Select a face in the 3D view to highlight the corresponding entry in the details tree. The converse is also true.
The following can be applied to faces:
  • Face medium
    • Metallic (to model skin effect).
    • Layered dielectric
    • Impedance sheets (to represent metal surfaces in cases where only the surface impedance per unit area is known).
    • Characterised surface
  • Coating (layered dielectric)
  • Dielectric sheet
  • Local mesh size
  • Solution methods
  • Basis functions (local setting)

When an operation results in a face being split into multiple faces, both the resulting faces inherit the properties of the parent.

For operations where multiple faces need to be merged but have conflicting properties, an assumption will be made and the face will be marked suspect to indicate that the settings need to be reviewed.
