Class
    Foam::solvers::multicomponentFluid
 
Description
    Solver module for steady or transient turbulent flow of compressible
    multicomponent fluids with optional mesh motion and change.
 
    Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and
    pseudo-transient and steady simulations.
 
    Optional fvModels and fvConstraints are provided to enhance the simulation
    in many ways including adding various sources, chemical reactions,
    combustion, Lagrangian particles, radiation, surface film etc. and
    constraining or limiting the solution.
