Hello everyone,
I am solving the Stokes equations using Raviart–Thomas elements in deal.II. When the boundary conditions are homogeneous Dirichlet, everything works fine and I observe the expected convergence behavior. However, when I switch to inhomogeneous Dirichlet boundary conditions, I encounter problems: although I apply ``VectorTools::project_boundary_values_div_conforming(...)`` to set the boundary values, the pressure error does not converge. Has anyone experienced a similar issue, or could point me to the right way of handling inhomogeneous Dirichlet conditions for the Stokes problem with RT elements? Am I missing an additional step to make the pressure converge? Any advice or references would be very much appreciated.
