Hi, I'm using LibMesh for meshing a non-linear equation. I want to use NRichardson non-linear solver to solve the equation. I have a Newton trust region non-linear solver as a pre-conditioner. Both these SNES are created via the LibMesh NonlinearImplicitSystem and PetscNonlinearSolver wrappers.
I need to re-init the LibMesh NonlinearImplicitSystem each time the preconditioner is applied. Also, I need the preconditioner to be solved via the LibMesh wrapper instead of directly through SNESSolve. How can make it work this way? Any help is appreciated! Thanks, Harshad
