Hi, I have earlier used GMSH ,sometime in August 2009, to work on some stl files. I was able to create geo files and then mesh the geometry using 3Dimensional elements. But recently when I tried to do the same action, I was getting an error saying the faces of the meshes are intersecting. Why is that I am not able to 3D mesh the same file now when I was able to do it some 5 months back? R
