Hello， I ran the example case 'r1854' in \nek_svn\examples\escudier, and I didn't changed anything, then I loaded the reults in VIsit 2.0. There seems some problem with the mesh. The image is attached. The nek source is the latest. How does this come out？ By the way, how can I make similar cylindrical mesh, is there examples or detailed description? Regards Bofu Wang
