Gmsh to OpenFOAM

OpenFOAM by default only works with 3D mesh elements, so some special steps need to be applied to create a 2D mesh. This is not meant to be a tutorial on GMSH or OpenFOAM, but just some useful steps to get the two tools to work together. Note that two ways of geometry generation are shown. One uses the GMSH GUI to create the geometry and. In this tutorial we import a mesh file genereted by Gmsh into openFoam, and solve the case of laminar flow past a 2D cylinder using pisoFoam.

For those still having a similar problem with the gmshToFoam utility, for me it turned out that the issue was due to a reduction of the write precision from 16 (gmsh) to 6 (OpenFoam). I was able to correct this by setting the appropriate precision in the system/controlDict:writePrecision entry of the OF case prior to running gmshToFoam Gmsh is a free open source meshing framework providing a couple of meshing algorithms such as structured and unstructured mesh generation of two- and three-dimensional meshes.
