Dear all
I am using parallel::distributed::Triangulation for a 3D problem.
*Case 1.* Suppose I create a 256^3 mesh like this
GridGenerator::subdivided_hyper_rectangle
Call for x,y,z
GridTools::collect_periodic_faces
triangulation.add_periodicity
then code runs for a very long time to do this, and on some machines
crashes with oom_kill error, which is related to out of memory error.
*Case 2.* It works fine if I do
GridGenerator::hyper_rectangle (initial mesh has single cell)
Call for x,y,z
GridTools::collect_periodic_faces
triangulation.add_periodicity
triangulation.refine_global(8)
However I have nonstandard grid sizes, e.g., 195x72x106 which cannot be
obtained by refine_global.
What options are there to improve the periodicity setup part.
Will parallel::fullydistributed:Tria help ?
thanks
praveen
