We investigate a numerical solutions for the melt crystal system during directional solidification. The approach is based on a homogeneous formulation of the conservation equations for the system undergoing a phase change. The solid and liquid phases are separated by an intermediate diphasic zone modelled as a porous medium. This formulation permits us to solve the solidification problem in a fixed mesh. The application concerns the steady and unsteady flows and the interactions between the melt and the solidification front. We consider the case of an inverted Bridgman configuration (the melt is below the crystal)
