Hi everyone, I am trying to implement an adaptive mesh refinement scheme for the Step-35 examle program. I implemented the mesh-refinement acording to the Step-26 tutorial.
So I proceeded in the refine_mesh function as follows: 1. Create a Solution_Transfer object for each Vector; 2. prepare refinement_and_coarsing; (here I also made a hangiing node constraint) 3. execute_ref_and_coars; 4. create_triangulation_and_dofs; 5. Interpolate_solution for each Solution_transfer vector; 6. finally distribute_constraints; But the problem is, that after one mesh-refinement step the time-step solving of the Navierstokesprojection (in Step-35 it is in diffusion_step()) diverges. And I don't see why. Does anyone have an idea? First I thought that I used the Boundary conditions in a wrong way during te refinement step, but the problem also comes up when I apply zero Boundary values on the whole domain for the velocity u. Tanks for your help.
