Re: [Getfem-users] Problem with getting convex structure

[julien pommier]

Hi Eugen,
You are right, this is a problem that I did not notice when we switched 
from numeric to numarray: the python numarray library does not support 
arrays of python objects, and since your mesh contains more than one 
convex structure, you have a problem. I just commited a fix to the 
getfem_python.c file:

http://svn.gna.org/viewcvs/getfem/trunk/getfem_matlab/src/python/getfem_python.c?rev=2509&r1=2318&r2=2509

So now arrays of getfem objects are just returned as regular python 
lists of getfem objects.
