script/extract_surface.py script

Given a mesh file, this script extracts its surface and prints it to stdout in form of a list where each row is [element, face, component]. A component corresponds to a contiguous surface region - for example, a cubical mesh with a spherical hole has two surface components. Two surface faces sharing a single node belong to one component.

With ‘-m’ option, a mesh of the surface is created and saved in ‘<original path>/surf_<original mesh file name>.mesh’.
