dolfin-tape's Issues

Questions about flux reconstruction

Hello, great work! Although I don't understand how the patches are built. What's the size of the patches? How many elements do they cover? I see that this is taken care of MeshColoring though. Also, what happens if there are neumann boundary conditions? How can they be taken into account?

EDIT: I modified the poisson example to include an imposed boundary flux and it seems that works, I don't know why though.
