I am new to PETSc and I am interested to use the nonlinear solver in a CFD code for low speed compressible fluid.
According to some papers, it seems that GMRES (or any other Krylov method) could be used to precondition FGMRES in a way that is completely matrix-free. Is it something possible with the fgmres implementation provided by PETSc ? Christine -------------- next part -------------- An HTML attachment was scrubbed...
