## 1 Solvers that fit into the OpenFOAM classification

These solvers fit into the classification, that is given by the directory structure of the solver-sources.

### 1.1 Basic

- potentialWaveFoam: A one-line solver that solves a wave equation,
`fvm::d2dt2(phi) == c * c * fvc::laplacian(phi)`.

### 1.2 Combustion

- reactingFoam: Adding ignition to reactingFoam.

- alternateReactingFoam: A library and a solver based on it that allow the usage of different chemistry engines for reacting flows

- edcPisoFoam: A specialised application for turbulent combustion modelling (non-premixed and premixed) based on the OpenFOAM® technology.

### 1.3 Compressible

### 1.4 DNS and LES

- PisoFoamSSD: A Low-Dissipative, Scale-Selective Discretization for PisoFOAM

### 1.5 Electromagnetics

- EHDFoam: A Numerical Model to simulate the multiphase flow in the electrostatic field, based on the Taylor-Melcher Leaky Dielectric Model

### 1.6 Financial

### 1.7 Heat transfer

- boussinesqBuoyantSimpleFoam: Incompressible thermal flow solver under Boussinesq approximation

- massBuoyantBoussinesqSimpleFoam: Steady-state solver for buoyant, turbulent, incompressible flows with vapor and contaminant scalar transport for HVAC and similar applications

### 1.8 Incompressible

- simpleScalarFoam: Steady-state incompressible laminar flow solver with scalar transport and mass transfer coefficient and Sherwood number calculation

- turbScalarFoam: Unsteady incompressible laminar flow solver with scalar transport and mass transfer coefficient and Sherwood number calculation

- icoBlockedCellFoam: Unsteady incompressible laminar flow solver with the possibility to exclude definite FV cells from the flow calculations

- icoDyMFoam: Unsteady incompressible laminar flow solver with the dynamically refined mesh according to the transported scalar distribution

### 1.9 Particles(Eulerian)

- SbmFoam: A suspension balance solver developed during a PhD for rigid spheres in fluid flows. It accounts for particles migration phenomenon (as a continuum approach).

### 1.10 Multiphase

Solvers for two or more interacting liquids

- compressibleMixingPhaseChangeFoam: Solver for two-phase flow of liquids with inter-phase mass change, buoyancy, temperature and pressure dependence for density

- RichardsFOAM: A solver for water flow in unsaturated porous media.

### 1.11 StressAnalysis

## 2 Other

These solvers don't fit into the standard scheme.

### 2.1 Turbulence Modeling

- turbFoamAverage with k-omega SST SAS: Includes the k- SST-SAS Equations and a modified version of turbFoam for this turbulence model.

### 2.2 Technology Demos

Solvers that demonstrate concepts, but haven't got a fully implemented physics.

- icoLagrangianFoam: Incompressible solver with particles. Demonstrates the use of Lagrangian-particles outside the dieselFoam solver

- icoStructFoam: Fluid-Structure interaction. Demonstrates the use of two coupled solvers and mesh motion

- interTrackFoam: Tracks a moving interface with a moving mesh, so that the mesh boundary remains coincident with the interface.

- solidParticleFoam: A minimalistic code and case set-up as an example of how to use the
`solidParticleCloud`class.

**Note to editors**: Use the solver name as the page name, when adding a new solver to this page, but prepend *custom* in order to avoid name clashes
