Hi,
is it possible that the boundary_ids have something to do with my
problem?
During the calculation I manually set the boundary ids by:
mesh.boundary_info->add_node (nod, idval);
mesh.boundary_info->add_side (elem,s, idval);
If I write the mesh before everything works fine. In contrast, if I do
it after setting the boundary ids, I can't write it any more (except
with gmv).
