I have been trying to convert my 2d mesh, generated with Triangles, to the .xml files fences requires for solving the stokes problem with Taylor-hood elements.
The 2 files fences needs are:
1] mesh.xml
2] mesh_subdomains.xml
However, after converting the triangle file to .xml using fenics convert with the following command:
dolfin-convert -i Triangle mesh mesh.xml
, only 1 file is generated, containing both domains and subdomains.
Any help/suggestion on a non-manual way to separate those 2 files would be welcome.
