Hello PETSc developer team, I am a user of DMPlex in PETSc with Fortran. I have two questions:
- Is DMLocalToLocal() now available for DMPlex with Fortran? I made similar inquiry before: https://www.mail-archive.com/[email protected]/msg44500.html - Is there any example that can see how DMCoarsen() works? I can see either src/dm/impls/stag/tutorials/ex4.c or src/ksp/ksp/tutorials/ex65.c from the example folder. However, it is a bit tough to get an idea of how DMCoarsen() works. What can be the "coarsening" criteria? Is it uniformly coarsening over the domain? or Can it be variable-gradient based? Having more examples would be very helpful. Thanks, Mike
