Dear PETSc team,
I would like to play with aspin-type nonlinear solvers. I have found several tests like snes/tutorials/ex19.c but they all use DA, which I don't want to use since I need to stick at the algebraic level. Then, I started looking at petsc4py/demo/ode/heat.py and tried to set up things. Unfortunately, I get the error "DM has no default decomposition defined. Set subsolves manually with SNESNASMSetSubdomains()" which, I think, I do understand. But I do not find any implementation of the SNESNASMSetSubdomains in petsc4py. Am I missing something ? Thanks, Nicolas
