[IDV #CQG-166832]: Volume Rendering NetCDF Files

> Dear Sir/Madame,

> I am using IDv for a project and have found it to be very useful. However I

I am guessing the problem you ran into is the vertical coordinate constructed 
incorrectly in the post process script
of the WRF output. You can check the script or send me a small sample file.
