Running Simulation - Parallel Run - Domain Decomposition
To run simulation in parallel the model regions have to be decomposed first. Utility decomposePar reads settings from system/decomposeParDict, it is recommended to use automatic decomposition method scotch.
There are a lot of turbulence models available in OpenFOAM. It is possible to list all of them, that can be used within simpleFoam with following command. # simpleFoam -listTurbulenceModels The same command also works with other solvers.
