Hi to all
I'm new user of O.F. and I've a problem.
I'm using blockMesh editor for create a simple model (in past i've used GMSH), but there is this error:

certainly there is a error in my geometry but I don't know exactly where........
Thanks in advantage

There is a -blockTopology argument to blockMesh which will dump an .obj file. Load this into e.g. javaview or with objToVTK into Paraview (which both can display vertex numbers). Helped me a lot finding block errors.
