Hello, I would like to use ASPIN preconditioner. However after setting up PETSC options and running it says: 0]PETSC ERROR: Object is in wrong state [0]PETSC ERROR: DM has no default decomposition defined. Set subsolves manually with SNESNASMSetSubdomains(). I have seen, that in DM, there is implemented domain decomposition: DMCreateDomainDecomposition_libMesh What is way of using this function? many thanks!
