| 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. | |
