Laplace smoothing is also performed for insert-edge-zone, remesh-overlapped-zones, and prism-retriangulation options. Smoothing is performed again.

remesh_face_zone(*args, **kwargs)#: Remeshes a specified face zone by automatically extracting edge loops. If edge loops are present in the current domain (for example, if they were created using the create-edge-loops command), they are used to remesh the specified face zone.

remesh_face_zones_conformally(*args, **kwargs)#: Remeshes face zones using the current size function and keeping a conformal interface between them. If no size function is defined, an error message will be generated. This command will prompt for: Boundary Face Zones Boundary Edge Zones feature angle – used to determine the minimum angle between features that will be preserved during remeshing corner angle – used to specify the minimum angle between feature edges that will be preserved Replace Face Zone? – (default is Yes) the remeshed face zone(s) will take the name and -id of the original zones, and the original face zone(s) will have “orig” appended to their name.
