[deal.II] Re: High order mesh from Gmsh

Hello everyone, Sorry to revive/hijack this thread, but it seems to have the exact information/people that might be able to help. My current goal is to perform some shape optimization with some h(p)-refinement. I am currently using Prof. Heltai's method described in this issue

[deal.II] Implementing periodic b.c.

I've never implemented periodic b.c. before and so I'm trying to figure out if I've done it correctly... especially since I find the documentation a bit confusing. In this case, I colorise the boundary of my square using the optional argument in GridGenerator and then try to build the periodic

[deal.II] Re: Configuration of PETSc

Hello Konrad, I thing PETSc PCILU does not work in parallel. You could use the preconditioner PETScWrappers::PreconditionBlockJacobi that uses an ILU preconditioner for each process block. https://www.dealii.org/current/doxygen/deal.II/classPETScWrappers_1_1PreconditionBlockJacobi.html Also

[deal.II] Configuration of PETSc

Dear deal.ii community, I am using deali.ii with PETSc and Trilinos. However, when I am using the PETSc PreconditionILU I get an error that suggests that a solver package is missing (with Trilinos it works). Petsc's PreconditionAMG works fine (although not very efficiently for my problem). Do
