[deal.II] project_boundary_values for Stokes equations

2018-02-21 Thread Stephen Shannon
I am solving the 2D Stokes equations with Dirichlet BCs, so I have 3 unknowns (u1, u2, p) with Dirichlet BCs on u1 and u2. Rather than interpolate, I'd like to project the Dirichlet boundary values. Looking at the documentation for VectorTools::project_boundary_values(), the description of

Denis, thanks a lot for your answer and links that you provided. However, my solution becomes in a way that the displacement values on that boundary abnormally grow even without assigning new boundary condition in a time loop. I attach figures on the zero step (correct) and on the first step
