1 centralFoam
1.1 Introduction
centralFoam is a compressible flow solver based on the family of central/central-upwind schemes. Initially developed to deal with non-viscous flows (see first document) it has been recently extended to viscous (yet only incompressible and laminar) flows and to low-Mach and truly incompressible flows through time-preconditioning. Furthermore R-K time integration and some standard convergence acceleration tecniques have been implemented (see second document).
Work is still ongoing (in my free time) towards full viscous (incompressible & compressible, laminar & turbulent) capacity and to improve performance when computing incompressible flows.

2.1 Introduction
MGsimpleFoam is an FAS-multigrid solver for incompressible viscous (yet only laminar) flow based on a new FASMGagglomeration class which takes care of automatically generating the required coarse-level meshs. It uses the 'SIMPLE' algorithm, similarly to the standard simpleFoam solver, as basic smoother in the multigrid process.
Work is still ongoing (in my free time) towards full viscous (laminar & turbulent) capacity and parallel computations on large 3D meshes.
Furthermore, the FAS-multigrid methodology might be extended, using the same FASMGagglomeration class, to most other solvers, including the compressible/incompressible flow solver centralFoam
