DOLFIN

Python interface of tabulate_facet_dofs in dolfin 1.1.0

Asked by Weiwei Wang

Hi,

tabulate_facet_dofs gives the following error message for dolfin 1.1.0,

 TypeError: in method 'GenericDofMap_tabulate_facet_dofs', argument 2 of type 'unsigned int *'

and a piece of code to repeat the error is:

from dolfin import *
import numpy as np

mesh = UnitCube(2,2,2)
V = VectorFunctionSpace(mesh, "CG", 1)
dm = V.dofmap()

d = np.zeros(dm.num_facet_dofs(),dtype='I')
dm.tabulate_facet_dofs(d,0)

which works fine with dolfin 1.0.0, does anyone know how to fix it please?

Best wishes,
Weiwei

The typemap for this disappeared in the big uint -> size_t change. I
have added it back for the 1.1.x repo. You need to pull the code from
the repo.

  bzr branch lp:dolfin/1.1.x dolfin-1.1.x

We have also discussed to release a point release of the 1.1.x branch
with some bug fixes soon.
