• 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:
