Dear Yves,
I have tried to write some codes like shown in the last of this email.
However, it is too difficult to finish it without a detailed understanding
of the class structures. It will be highly appreciated if you can give me
some advise.
sincerely
Tsai
dal::bit_vector MeshRegion_points_index(const getfem::mesh& mesh,unsigned
int rg_id)
{
dal::bit_vector temp;
for (getfem::mr_visitor i(mesh.region(rg_id)); !i.finished(); ++i)
{
temp[??]=true;
}
return temp;
}
