Re: [deal.II] Problem with PETScWrappers::SolverCG

Dear Hamed, You are duplicating your posts in two threads. This is not productive, so I'm going to ask you to please focus this topic within your other thread . You have been given some useful advice there that you should follow up on.

[deal.II] Easy way to calculate second-deviatoric tensor

Hi, all. I am really receiving a lot of help from this group whenever I visit here. I have a question today. I am developing FEM code for analyzing non-newtonian fluids using deal.ii library, which is amazing tool. In many cases, I have to calculate 'The second invariant of rate-of-str

Another point I need to mention is that I had the same problem when as my first try of parallelization, I paralleled a much simpler code, the step-25, based on the step-40 . I received the same Segmentation Violation error from Petsc. At that time, I replaced PreconditionerAMG with Precondition

Re: [deal.II] Problem with PETScWrappers::SolverCG

Timo, Step-40 works on my machine perfectly. The code and its dependent parameter file are attached. I appreciate it if you could run the code on your machine and see what's the problem with it. Thanks On Sunday, October 16, 2016 at 7:55:35 AM UTC-5, Timo Heister wrote: > > > I have paralleli

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

Even if I implement Trilinos It terminates with the following Petsc error: "PETSC ERROR: Caught signal number 11 SEGV: Segmentation Violation, probably memory access out of range" On Sunday, October 16, 2016 at 10:39:49 AM UTC-5, Daniel Arndt wrote: > > In case there is an error with Trilinos,

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

Daniel, Let me explain the problem more. I heve parallelized a code based on step-40. The non-parallel code works for all the initial values and boundary conditions But the parallel one fails at the first call to solverCG with this error: "[0]PETSC ERROR: Caught signal number 11 SEGV: Segment

In case there is an error with Trilinos, what is it? Am Sonntag, 16. Oktober 2016 17:27:26 UTC+2 schrieb Daniel Arndt: > > Hamed, > > It still works with Petsc and Trilinos is not implemented at all. I appreciate it if you could let me know what changes should be made in step-40 t
