TCFD solver for transient, cavitating fluid flow is called greenDyMSolver. It was gradually developed during the time from the interPhaseChangeDyMFoam solver. In any matters the greenDyMSolver 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, limits for variables can be specified and many other changes have been done.
