Hi, For the smoother in PCMG, I want to use a red-black block Jacobi smoother. Is this available with the existing PETSc options? If so, how do I designate which blocks are red and which are black?
If it is not possible, what would be the best way to implement this? Would I use KSPRICHARDSON+PCSHELL? Thanks! -- Ben Yee NERS PhD Candidate, University of Michigan B.S. Mech. & Nuclear Eng., U.C. Berkeley
