Run the program as ./enosh (make sure it is executable). You can find a test.cfg file in this zip file and it shows how you can make it work. The .cfg file syntax is similar to OpenFOAM’s native mesh generator. Please let me know if you have any problems with it.
Also, after you export it to OpenFOAM mesh, please run renumberMesh -overwrite and then use checkMesh -constant to make sure the mesh is okay.
