Greetings, I hope you are doing great.
We are currently working on parallel solver employing PETSc for the main numerical methods (GMRES, Newton-Krylov method). We would be interested in combining the PETSc solvers with the AMR framework provided by the library AMReX (https://amrex-codes.github.io/amrex/). I know that within the AMReX framework the KSP solvers provided by PETSc can be used, but what about the SNES solvers? More specifically, we are using a DMDA to manage parallel communications during the SNES calculations, and I am wondering how it would behave in a context where the data layout between processors is modified by the AMR code when refining the grid.
Would you have any experience on this matter ? Is there any collaboration going on between PETsc and AMReX, or would you know of a code using both of them?
Respectfully, Pierre Bernigaud
