Hello, I intend to use RT elements for my fluid flow problem and the test case (2D) is shear flow. Consequently the I need to apply constant shear/sliding velocity (u_x = shear_velocity, u_y = 0) at top and bottom boundaries and velocities of form u_y = 0, u_x = y*shear_velocity for the right and left boundaries. I came across the function VectorTools::project_boundary_values_div_conforming <https://www.dealii.org/developer/doxygen/deal.II/group__constraints.html#ga86427a4e8b3a7e580dabb4e473005288> () that helps to apply inhomogeneous dirichlet bcs but only in the normal direction (normal to boundary face), but what I also intend to do is apply dirichlet bcs for non-normal component (i.e. for u_x at top and bottom boundary) for RT elements. Is there any way out?
Please note that we can not simply use VectorTools::interpolate_boundary_values() for RT elements.
