[sfepy] Re: Several questions for solving a linear elastic problem

For one of my questions: I found a way to extract the surface facets of the 3D object by using:

surface = domain.create_region('Surface',
                           'vertices of surface',
                           'facet')

The result is a number of facet indexes. Could you provide more details about the indexing of the facets according to the mesh definition? In my understanding I will need that to match the force vectors at the surface with the corresponding facet. Thank you again.
