32 Description
33  Transient cavitation solver based on the homogeneous equilibrium model
34  from which the compressibility of the liquid/vapour 'mixture' is obtained,
35  with optional mesh motion and mesh topology changes.
36 
37  Turbulence modelling is generic, i.e. laminar, RAS or LES may be selected.
