Hi again,
Just to precise that you need to compile sel2vtk.f90 in order to create an executable. You don't use it via paraview, I am not sure if I understood correctly your message. Pay attention, the script.sel2vtk.sh provided is for linux, you need to create a windows equivalent, or just type in the two command lines in a prompt command window.
Finally, you can also of course use postel3d to extract your results on a given plane (horizontal or vertical). But here also, there seems to be a persistant bug in v6p3 with python (also a date format problem). You need to go back to v6p2 have it working. Hopefully this can be solved in a next release...
Good luck,
PL
