Hey John, thanks for your reply, here is the diff file.

Hi Ping, I'd be happy to take a look at your patch. Would you mind sending me the diffs in the 'svn diff' format? If you have an SVN checked-out copy of the source tree, just run 'svn diff', if not just send me your vtk_io.C file directly and I'll take a look.

In most cases it works pretty well, except the HEX27 elements. So I made a few modifications in the source code, and made it work. I guess maybe I just post it here, maybe someone can update it to the subversion, if nothing is wrong, of course. ------------------------------------ file: mesh\vtk_io.C line 215 ------------------------------------ ... case HEX27: celltype = VTK_TRIQUADRATIC_HEXAHEDRON; //Added line break; // 29 Added line .... ------------------------------------ file: mesh\cell_hex27.C line 460 -560 ------------------------------------ // according to the VTK documentation http://www.vtk.org/doc/nightly/html/classvtkTriQuadraticHexahedron.html // I change the connectivtiy mapping.
