Re: [deal.II] compress error for vector of PETScWrappers::MPI::SparseMatrix

Daniel and Dr Bangerth, Thanks for the help. I got it resolved with modifying the dsp. That does be my misunderstanding, hahaha. Best, Weixiong 在 2017年6月7日星期三 UTC-7上午10:33:57，Wolfgang Bangerth写道： > > On 06/07/2017 11:14 AM, Weixiong Zheng wrote: > > > > I see your point. I would double check

Re: [deal.II] compress error for vector of PETScWrappers::MPI::SparseMatrix

Daniel, I see your point. I would double check later. The reason I didn't use locally relevant dofs is I didn't design the code to do h-refinement so I didn't see points using relevant dofs. Thanks, Weixiong 在 2017年6月7日星期三 UTC-7上午6:35:44，Daniel Arndt写道： > > Weixiong, > > [...] >>

[deal.II] GridGenerator::extract_boundary_mesh for parallel::shared::Triangulation

Hi all, I am trying to reproduce the code in Step 38 that extracts the boundary mesh, but I'd love to use a parallel::shared::Triangulation rather than a Triangulation class. In a nutshell, I did this: template class

Re: [deal.II] Re: Problem with postprocessor

Hi Seyed, I am old-fashioned in this sense: indeed yes, I just plot the output into a file: make run | tee my_results.txt Then I `grep' the quantity (for example PStress) that I want and then plot with gnuplot. Of course it would be a bit more efficient to write all output of interest
