Dear all,
I am coding up a code such that DG is used in one subdomain, while CG is
used in all other subdomains. The implementation is with hp::FECollection
class. As the CG-subdomains are discontiguous, i.e. they are spatially
disconnected, can I still use only one FE_Q for all disconnected

Dear Daniel,
You can obtain local DoF values from a global FE vector using

just do
std::cout << (int)cell->face(face_number)->boundary_id() << std::endl;

Hi,
Sorry to disturb again, I have a problem. :)
The following line gives me a headache:
std::cout << cell->face(face_number)->boundary_id() << std::endl;
... since I cannot see anything. It outputs strange symbols such as � or
some 0001 cube.
