Hi,
Currently looking to implement free-slip for my Navier-Stokes solver, but I’m not sure how this would work. Thus far I’ve used VectorH1() with dirichlet and “do-nothing” boundary conditions, but I need to specifiy that one component has 0 velocity, while another is free to change. I suppose I could do something like V = H1*H1 with different boundary conditions, but is there some other/cleaner way to do it?
Thanks!
