A region is an enclosed volume. By default, a region is set to perfect electric
conductor (PEC).
Selecting a region in the 3D view selects the corresponding region in the details tree. Conversely, selecting a region in the details tree
selects the corresponding region in the 3D view.
Figure 1. Select a region in the 3D view to highlight the corresponding entry in
the details tree. The converse is also true.
The following can be applied to regions:
Media
Dielectrics
Anisotropic media (3D)
Local mesh size
Solution methods
Basis functions (local setting)
Boolean operations can be applied to the parents of regions. Where geometry operations
introduce intersections of existing regions, and the parent regions have conflicting settings,
the resulting regions are marked suspect to indicate that the settings need to be
reviewed.
Note: Deleting a face that forms part of the region boundary effectively removes the region or
merges the region with the surrounding region.
Any setting applied to a region is also used for faces bounding the region.
Attention: If the face has a conflicting setting, the face setting takes precedence
over the region setting.
