Hi there I have posted a couple of previous similar questions, but have had no response, so I thought I'd try again.
I am solving eigenvalue problems derived from Maxwell's equations using pydolfin (or trying to) making use of the edge-based Nedelec elements. I am able to assemble the finite element matrices with no problem, but I am struggling to apply the Dirichlet boundary conditions on the mesh - basically I need to remove the rows and columns of the matrices associated with the edges (in 2D, faces in 3D) on the mesh boundary so that I can solve the resultant eigenvalue problem. Any help in applying these boundary conditions would be much appreciated.
