[petsc-dev] DM not propagating into Fieldsplit when using external DMShell?

2018-09-24 Thread Boris Boutkov
Hello all, I am trying to solve a Stokes type problem using PETSc's Fieldsplit infrastructure while providing external GMG information coming from libMesh and am running into issues when using the two simultaneously. I have verified that FS + MG behaves as expected on its own, (I can use

Thanks for the prompt reply and clarifications! 2) Could you be more specific about what should be different? It sounds > like you want "your" DM attached to the (0,0) block so that > you can do GMG on the Laplacian there. > Exactly. This works if I use pc_type gamg on the (0,0) block, but
