[deal.II] Re: Seg fault using Extracting hanging node dofs in MPI

2017-12-09 Thread Daniel Arndt
Phani, apparently no one used this function for a parallel::distributed::Triangulation before. The problem is that we don't know about DoFs on artficial cells. The pull request https://github.com/dealii/dealii/pull/5604 fixes this issue by extracting DoFs belonging to locally owned cells. Essen

Oh thank you very much for the pull request. For now, I was extracting DoFs corresponding to hanging nodes by using is_constrained(dof).in parallel. On Sat, Dec 9, 2017 at 6:26 AM, Daniel Arndt < daniel.ar...@iwr.uni-heidelberg.de> wrote: > Phani, > > apparently no one used this function for a

Juan, take a look at the documentation of that function. It tells you that the last parameter needs to be "false", i.e. this function is only implemented for the case in which you don
