Boundary Conditions for Test functions

0 votes

I have a problem which requires the solutions to satisfy periodic boundary conditions but I would like the test functions to vanish on the boundary for the sake of my weak formulation.

Wondering how this might be done? Or is this implemented automatically by definition of FEniCS testfunctions?

Thanks.

Chapter 2 might be a good source:

It's handled 'automatically'

There is a periodic demo, if you haven't seen it yet in demo/documented/periodic.
