Comments
 Input is general, no prior assumptions are enforced! You must verify that the elementary boundaries are consistent with general assumptions of ALE (equation closure).
 Density, pressure, energy are imposed according to a scale factor and a time function. If the function number is 0, the scale factor input is used as a contstant imposed density, pressure or energy.
 The INLET boundary condition is only compatible with /MAT/LAW151. Inlet functions for volume fraction, density and pressure (or energy depending on the formulation VP or VE) must be provided for every phase present in the /MAT/LAW151 card.
 If the function ID that defines the volume fraction, velocity, density, pressure or energy is equal to 1, the corresponding physical quantity is interpolated from the inside of the domain (zeros normal derivative).
