GambitToFoam
From OpenFOAMWiki
This application converts a Gambit mesh into the OpenFOAM format. Note that when you export a mesh from Gambit (creating a file with a .msh extension) you should use fluentMeshToFoam instead.
To export a Gambit mesh, choose the solver to be "Generic" and then choose export mesh from the pull-down menu.
