Concerning a general CFD unstructured grid case, what is the most efficient matrix solver so far or in the near future that can solve the matrix really fast with thousands of CPUs.I am using OpenFOAM to do the simulation of incompressible flow. It uses OpenMPI to run the parallel jobs. The simulation is 2D or 3D, and uses a finite volume discretization. I'd like to run very large case studies, with around 10 million to 1 billion grid points. For these case studies, I need the solution over a long time interval.
