OpenFOAM v11 User Guide - 3.5 Solver modules

3.5 Solver modules

From OpenFOAM version 11, application solvers, e.g. simpleFoam have been largely replaced by the generic foamRun solver which loads a solver module, e.g. incompressibleFluid that defines the flow solution. Solver modules are located in the $FOAM_APP/modules directory. The current solver modules distributed with OpenFOAM are listed below.

3.5.1 Single-phase modules

fluid

Solver module for steady or transient turbulent flow of compressible fluids with heat-transfer for HVAC and similar applications, with optional mesh motion and change.

incompressibleDenseParticleFluid

Solver module for transient flow of incompressible isothermal fluids coupled with particle clouds including the effect of the volume fraction of particles on the continuous phase, with optional mesh motion and change.

incompressibleFluid

Solver module for steady or transient turbulent flow of incompressible isothermal fluids with optional mesh motion and change.

multicomponentFluid

Solver module for steady or transient turbulent flow of compressible multicomponent fluids with optional mesh motion and change.

shockFluid

Solver module for density-based solution of compressible flow

XiFluid

Solver module for compressible premixed/partially-premixed combustion with turbulence modelling.
