executed with foamRun for single region simulations of foamMultiRun for
multi-region simulations. Replaces pimpleFoam, pisoFoam and simpleFoam and all
the corresponding tutorials have been updated and moved to
tutorials/modules/incompressibleFluid.
Class
Foam::solvers::incompressibleFluid
Description
Solver module for steady or transient turbulent flow of incompressible
isothermal 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, constraining or limiting
the solution.
