pb_fronttracking_disc

Synonyms: probleme_ft_disc_gen

The generic Front-Tracking problem in the discontinuous version. It differs from the rest of the TRUST code : The problem does not state the number of equations that are enclosed in the problem. Two equations are compulsory : a momentum balance equation (alias Navier- Stokes equation) and an interface tracking equation. The list of equations to be solved is declared in the beginning of the data file. Another difference with more classical TRUST data file, lies in the fluids definition. The two-phase fluid (Fluide_Diphasique) is made with two usual single-phase fluids (Fluide_Incompressible). As the list of equations to be solved in the generic Front-Tracking problem is declared in the data file and not pre- defined in the structure of the problem, each equation has to be distinctively associated with the problem with the Associer keyword.
