TCFD solver for steady state, cavitating fluid flow is called greenSolver. It was gradually developed during the time from the interPhaseChangeFoam solver. In any matters the greenSolver behaves the same way as any standard OpenFOAM solver. It is compatible with all OpenFOAM applications and libraries. Solver is modified to be more robust, it can use MRF method, limits for variables can be specified and many other changes have been done.
