Description :

General function for querying information about convex_structure objects.

The convex structures are internal structures of GetFEM. They do not contain points positions. These structures are recursive, since the faces of a convex structures are convex structures.

Command list :

n = gf_cvstruct_get(cvstruct CVS, 'nbpts')

Get the number of points of the convex structure.

d = gf_cvstruct_get(cvstruct CVS, 'dim')

Get the dimension of the convex structure.

cs = gf_cvstruct_get(cvstruct CVS, 'basic structure')

Get the simplest convex structure.

For example, the ‘basic structure’ of the 6-node triangle, is the canonical 3-noded triangle.

cs = gf_cvstruct_get(cvstruct CVS, 'face', int F)

Return the convex structure of the face <literal>F</literal>.

I = gf_cvstruct_get(cvstruct CVS, 'facepts', int F)

Return the list of point indices for the face <literal>F</literal>.

s = gf_cvstruct_get(cvstruct CVS, 'char')

Output a string description of the cvstruct.

gf_cvstruct_get(cvstruct CVS, 'display')

displays a short summary for a cvstruct object.
