From what I could tell, the appropriate distribution of OpenFOAM ships with cfMesh. I was trying to use it on a Windows machine and they use the weird Linux shell available there. I found I was unable to navigate a directory system from that shell and troubleshot it for a while. Not being excited about a command-line only UI, I redoubled efforts on snappy. If you haven’t tried following @DaleKramer’s excellent advice in my recent thread, I’d suggest you take a moment to try it. Worked wonderfully.
