Re: [deal.II] Re: How to use Trilinos instead of Petsc in step-40

Hamed, running your code with a Trilinos installation alone fails for me in line 1617 with An error occurred in line <279> of file in function void dealii::TrilinosWrappers::SolverBase::do_solve(const dealii::TrilinosWrappers::PreconditionBase&) The violated condition was: false

Re: [deal.II] trouble running new step-55

Thank you Martin Where is developer version 8.5.0-pre? I installed dealii using candi, which I find very easy. candi can install dev version 8.5.0-pre? Cheers Franck 2016-10-17 12:29 GMT+02:00 Martin Kronbichler : > Dear Franck, > > I justed checked on my

Dear Lisa, A quick google search returned GridTools::find_cells_adjacent_to_vertex . Is this what you're looking for? Regards, J-P On Monday, October 17, 2016 at 1:01:57 PM UTC+2,

[deal.II] Re: Solution Components of a Vector valued problem

Hello, Thanks for the reply. I did it with iteration over all cells and vertexes of each cell. Is there any effective way to do it without iteration over cells? For example something like inverse of cell->vertex_dof_index

Re: [deal.II] trouble running new step-55

Dear Franck, I justed checked on my machine and it works both on an installation that only provides Trilinos and on an installation that has both (and where PETSc is selected). It looks like your installation is 8.4.0 whereas I think that step-55 requires the current developer version
