Detailed 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.
