Support for hybridization/static condensation and face DOFs?

Question

Dear Fenics users,

I was wondering if face finite elements (DOFs only live on the mesh skeleton) are implemented in Fenics already or not.
If so, I was wondering if static condensation can be manually implemented by explicitly looping over elements (with a local solve to static condense volume DOFs) to assemble the linear system for face DOFs. Then, we can talk about hybrid DG in Fenics.

I didn't find anything related in this direction...certainly, there are other softwares allow static condensation. e.g. Deal.II and NGsolve. Shall we work on this if nothing is there yet?
That would then be very cool...

Best,
Guosheng

It's under development. The issue is at https://bitbucket.org/fenics-project/dolfin/issues/387. Hopefully it will be available in the next few months.
