Dr. Bangerth Thank you, I just fixed up what was wrong... in most cases, it is usually easy problems. The manufactured solution of velocities has not satisfies the continuity equation. (i.e. manufactured solution does not satisfy, div.u=0)... Jaekwang Kim -- The deal.II project is lo

Thanks a lot! I will have a look at it, kind regards, Giulia Il giorno giovedì 9 febbraio 2017 15:19:07 UTC+1, Wolfgang Bangerth ha scritto: > > > > as far as I have understood (but I might be wrong), the functions > > VectorTools::interpolate_boundary_values > > < > https://www.dealii.org/8.4.

[deal.II] Renumbering dofs with petsc + block + MPI + Direct solver work around

A problem I am working on results in a non symmetric 4x4 block matrix system with the first block representing a vector valued velocity and the remaining 3 blocks scalar quantities that are all coupled. The fe system is represented as FESystem (FESystem(FE_Q (parameters.degree_of_fe_veloci

[deal.II] Re: Renumbering dofs with petsc + block + MPI + Direct solver work around

Hi, this is not the answer to your question but if I understand correctly, everything works fine with Trilinos and the only reason why you need PETSc is to use MUMPS. If that's the case, instead of using Amesos_KLU with Trilinos, you can use SuperLU_dist (http://crd-legacy.lbl.gov/~xiaoye/Supe

[deal.II] Re: Renumbering dofs with petsc + block + MPI + Direct solver work around

Interesting, I wondered if SuperLU_dist might be parallel but I hadn't looked into it yet. If it does work, then that certainly makes things much simpler since I have trilinos integrated well. I will look into installing it and see if it will work. I see what you mean by it not being the easi

Re: [deal.II] Re: Renumbering dofs with petsc + block + MPI + Direct solver work around

Actually Mumps is included in the Amesos solver used by TrilinosWrappers::SolverDirect("Amesos_Mumps"). You may have to recompile Trilinos with the corresponding flags to enable it (and probably deal.II as well). Am Donnerstag, 9. Februar 2017 20:52:16 UTC+1 schrieb Bruno Turcksin: > > 2017-02-
