The problem is that I am working on nonnative PETSc data; so I am not sure which recent methods would support shell approach. All I want is to use PETSc's algorithm for solving multicomponent system of equation. I am not bothering about preconditioning yet, as I will be trying a custom preconditioner down the road. -- Amneet -------------- next part -------------- An HTML attachment was scrubbed...
