Detailed Description

Solver module for steady or transient turbulent flow of compressible 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, Lagrangian particles, surface film etc. and constraining or limiting the solution.
