Hello Sambit, Can you try doing this? Also move the vertices of the ghost cell and avoid calling dftPtr->triangulation.communicate_locally_moved_vertices(locally_owned_vertices);
When I tried to use triangulation.communicate_locally_moved_vertices(locally_owned_vertices) last time, something wierd (Dont exactly remember what, Code was not doing what I was expecting) happened with me. But Since then, I have avoided using it. Thanks. On Monday, December 4, 2017 at 1:22:37 PM UTC-5, Sambit Das wrote: > > Hello Dr. Arndt, > > Thank you for your reply.
