Hi everyone I am trying to impose periodic boundary conditions for a flow problem using Stokes-Brikman equations. I need to impose periodicity parallel to the pressure drom and normal to it. And this may be a bit tricky.I am able to get the dofs for the two periodic faces and match them.However, I think I must find a way to exclude the pessure dof from the vertices and from the imposition of periodicity.Either way, does anyone know how I can do that?Currently, I am using a command of the form Face->get_dof_indices(vector<unsigned> dofs);
Which gives me all the dofs indices on the face.Are these dofs meant to be ordered in the sense: first say velocity and then pressure?or the indices are arbitrary?When intiallizing the FESystem object I first intialize the velocity approximation and then the pressure if this has anything to do.
