Dear all, I hope you are well. I am currently trying to solve an advection-diffusion equation at very, very high Péclet number. I first implemented a GLS-stabilized continuous Galerkin solution, it works well, but clearly I think a DG approach would be immensely better here.
The issue is that the velocity field for my advection-diffusion stems from a Continuous Galerkin solution with another dof handler, formulated using a FESystem. Everything work well until them. The issue I have is that the FEInterfaceValues does not seem to want to work with FEValuesExtractors? It seems like it cannot use the [] operator to extract my velocity values out of my 4 components (velocity + pressure). I am sure i'm forgetting something stupid here, but how should I proceed for vector valued problem using DG?
