Dear Roberto, I think the problem is that you are using GridTools::transform (via GridTools::rotate), in a distributed triangulation. This should not be done, as noted here: https://www.dealii.org/8.5.0/doxygen/deal.II/namespaceGridTools.html#a212e99cf0d923cebfa04f1d23fa60b04
If this is indeed the root of the issue, I see two options: 1. Rotate your problem, rather than your triangulation, 90 degrees. 2. You can create a temporary local normal triangulation, rotate it, and finally copy into the distributed triangulation. That is, something in the lines of >> Triangulation<2> tri_tmp; > > GridGenerator::hyper_cube_slit(tri_tmp, -1, 1, false); > > GridTools::rotate(-M_PI/2, tri_tmp); > > >> triangultion.copy_triangulation(tri_tmp); > > triangulation.refine_global (6); > > Bests, Lucas On Thursday, 12 April 2018 00:54:05 UTC+2, Roberto Porcù wrote: > > Dear all, > > in the reply to my first post I forgot the code. > I attach it to this reply. > > Best > > Roberto P. > > > On Tuesday, February 20, 2018 at 7:27:37 PM UTC-5, Roberto Porcù wrote: >> >> Dear all, >> >> I'm solving a linear elasticity problem on a cracked domain created by >> means >> of the GridGenerator::hyper_cube_slit function. >> When I solve it in serial everything works fine. >> When I solve it in parallel I get a problem on a node which is on one >> of the slit boundaries as it is possible to see from the attached >> pictures. >> I don't understand why that is happening because I wrote other parallel >> codes in deal.II >> and everything was always working fine.
