How to use CGNS file & create...
You're probably better off asking that on a software forum. I don't really know what this software is for (Something to do with databases from what I've just glimpsed) but if you look through there site there seems to be extensive documentation and a users guide. Maybe start there?
What exactly is it you're trying to do?
PS: Title spelling fail. :P
Edit: Nevermind, this seems to be a software forum too! (Just saw Computer and Technology section)
Separate names with a comma.
