OpenFOAM v12 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_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.

3.5.2 Multiphase/VoF flow modules

compressibleMultiphaseVoF

Solver module for the solution of multiple compressible, isothermal immiscible fluids using a VOF (volume of fluid) phase-fraction based interface capturing approach, with optional mesh motion and mesh topology changes including adaptive re-meshing.

compressibleVoF

Solver module for for 2 compressible, non-isothermal immiscible fluids using a VOF (volume of fluid) phase-fraction based interface capturing approach, with optional mesh motion and mesh topology changes including adaptive re-meshing.

incompressibleDriftFlux

Solver module for 2 incompressible fluids using the mixture approach with the drift-flux approximation for relative motion of the phases, with optional mesh motion and mesh topology changes including adaptive re-meshing.

incompressibleMultiphaseVoF

Solver module for the solution of multiple incompressible, isothermal immiscible fluids using a VOF (volume of fluid) phase-fraction based interface capturing approach, with optional mesh motion and mesh topology changes including adaptive re-meshing.

incompressibleVoF

Solver module for for 2 incompressible, isothermal immiscible fluids using a VOF (volume of fluid) phase-fraction based interface capturing approach, with optional mesh motion and mesh topology changes including adaptive re-meshing.

isothermalFluid

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

multiphaseEuler

Solver module for a system of any number of compressible fluid phases with a common pressure, but otherwise separate properties. The type of phase model is run time selectable and can optionally represent multiple species and in-phase reactions. The phase system is also run time selectable and can optionally represent different types of momentum, heat and mass transfer.

multiphaseVoFSolver

Base solver module for the solution of multiple immiscible fluids using a VOF (volume of fluid) phase-fraction based interface capturing approach, with optional mesh motion and mesh topology changes including adaptive re-meshing.

3.5.3 Solid modules

solid

Solver module for thermal transport in solid domains and regions for conjugate heat transfer, HVAC and similar applications, with optional mesh motion and mesh topology changes.

solidDisplacement

Solver module for steady or transient segregated finite-volume solution of linear-elastic, small-strain deformation of a solid body, with optional thermal diffusion and thermal stresses.

3.5.4 Film modules

isothermalFilm
