Meshes in OpenFOAM

OpenFOAM uses Cartesian coordinates.
All the cases in OpenFOAM are computed as to be three-dimensional. Even if the case is one-dimensional or two-dimensional, it is necessary to have at least one volume cell in each axis direction.
In general, there are four ways how to create mesh for OpenFOAM:
- Creating mesh in blockMesh – part of OpenFOAM
- Creating mesh in snappyHexMesh – part of OpenFOAM
- Creating mesh in foamyHexMesh – part of OpenFOAM
- Creating mesh with third party tools and importing it.
- OpenFOAM supports following mesh conversions:
  ansysToFoam
  cfx4ToFoam
  datToFoam
  fluent3DMeshToFoam
  fluentMeshToFoam
  foamMeshToFluent
  foamToStarMesh
  foamToSurface
  gambitToFoam
  gmshToFoam
  ideasUnvToFoam
  kivaToFoam
  mshToFoam
  netgenNeutralToFoam
  plot3dToFoam
  sammToFoam
  star3ToFoam
  star4ToFoam
  tetgenToFoam
  vtkUnstructuredToFoam

The general settings are displayed in Figure

The entry “Setup file” contains full path of a TCFD setup file, which has been used to initialize the fields in the form. It is empty if no such file has been used. However, it is always possible to load a new file into the form by pressing “Load…” and selecting a new file from the dialog window. The other three buttons “Reload”, “Save As…” and “Save” have obvious meaning. The same restriction for the usage of File > Save data… holds also here: One must press Apply before saving the results.
“Check Setup” button serves as a controling unit of current TCFD setup. It shows which part of the setup is missing or is inconsistent with other parameters.
The entry “Simulation type” offers selection of the type of the machine that is to be set up. CFD Processor supports the following machines: fan, propeller, pump, stator, virtualTunnel, turbine, hydro (water) turbine and wind turbine. Each of these types is slightly different, whether due to a different assignment of boundary conditions, or the postprocessing tools used.
