Re: [petsc-users] Understanding DMPlexDistribute overlap

Hi Michael, thank you for verifying that the test works. I actually was on `maint`, as per https://www.mcs.anl.gov/petsc/download/index.html. Now that I switched to `master ` everything works as expected, both my test example and the DMPlex test ex12, which I can now build without issue. I

Re: [petsc-users] Understanding DMPlexDistribute overlap

Hi Francesco, Ok, I can confirm that your test runs fine for me with the latest master branch. I'm attaching the log for two processes up to overlap 7, where the entire mesh is effectively replicated on each partition. The command I ran was: for OL in 1 2 3 4 5 6 7; do mpiexec -np 2 python

Re: [petsc-users] Understanding DMPlexDistribute overlap

Hi Michael, thanks for the prompt reply! While I am happy I mostly got it right, this means I have some kind of problem I cannot solve on my own. :( I have this very simple 2D mesh I am experimenting with: a rectangle with 64 vertexes and 45 cells (attached in exodus format as cantilever.e);

Re: [petsc-users] Understanding DMPlexDistribute overlap

Hi Francesco, Your description is almost correct: the overlap defines the topological depth of shared entities as counted in "neighboring cells", where a cell counts as a neighbor of an owned cell according to the defined adjacency style. So for overlap=0 only facets, edges and vertices may

[petsc-users] Understanding DMPlexDistribute overlap

Dear all, I was playing with DMPlex objects and I was trying to exactly figure out what the `overlap` parameter in DMPlexDistribute does. From the tutorial "Flexible, Scalable Mesh and Data Management using PETSc DMPlex" (slide 10) and from the work by Knepley et al. "Unstructured Overlapping
