Thanks! I tried to anisotropically refine and coarsen a parallel::distributed triangulation and saw that it didn't work. Subramanya. सुब्रह्मण्य . On Tue, Dec 3, 2024 at 8:31 AM Daniel Arndt wrote: > Subramanya, > > the anisotropic refinement support is pretty limited and won't work > with p

Thanks Martin for all the help! If I understand correctly, the first approach would assume that both the problems are solved in a fully coupled manner, with all fields updated simultaneously at each solve. For a staggered solution , where I solve the temperature first, and then the stress - I'd eit

Are you making sure you’re initializing the vector to 0 in release mode. Subramanya. सुब्रह्मण्य . On Sat, Feb 8, 2025 at 4:56 PM Junxiang Wang wrote: > In the first 80 steps, RHS and Stiffness are all the same. After several > step of refine mesh, the RHS then turns to different from the seri
