Simulation by the Mah-3 code of the interfaces using an mixed cells and markers

The calculated system depending on a priori information on the problem is presented by a set of computational domains. The domain each is a topological parallelepiped. The domain boundaries may be contact or external borders of the problem. In each domain one uses a regular, arbitrary hexahedral grid of its own (Fig. 1). The radius vector r and velocity vector u are related to the cell vertices, the density ρ , the pressure p , and specific intrinsic energy e are related to the cell geometrical center. The difference method is based on splitting into Lagrangian and Eulerian stages.
