[Paraview] Paraview 3.6.1 and netCDF 4

[Matthew Dillon]

All,

Thanks for the input on this one. I did some further investigation  
into this... it seems the "problem" lies with the netcdf4-python  
interface. I set up some scripts to generate identical files using A)  
ncgen, and B) netcdf4-python. The ncgen files are always recognized in  
Paraview (quite smoothly, I might say), while the netcdf4-python files  
aren't recognized. I'm not too sure what I am doing wrong with the  
python interface, but this clearly isn't the place for that. I am not  
going to get too worried about this, it doesn't seem to be a big issue  
one way or the other.
As well, thanks David for the information on xdmf, I helped clear some  
things up.
Thanks everyone for your help, I really appreciate it.
