Thanks for that explanation. I'll use the boundary integral like in step-20. When you say "the DG elements have no degrees of freedom on faces, they are all located in the interior of the cell", I understand how that's true for degree 0, but I'm guessing it's only in the "logical" sense for

[deal.II] interpolate_boundary_values not adding to ConstraintMatrix

Hi, I'm working on a flux-pressure model using a Raviart-Thomas/DGQ FESystem. I'm using Dirichlet conditions on the RT (flux) elements on part of the domain and on the DGQ (pressure) elements on another part of the domain using the boundary_id's. I'm using
