[IDV #WAC-705632]: Error: FlatField: RangeUnits must be convertable with RangeType default Units

Jeff,

First, update your IDV. It is very old.

http://www.unidata.ucar.edu/downloads/idv/current/index.jsp

Second, please respond with the full Jython function you are trying to write.
(I could not find it in the bundle.)

Also please upload the GrADS file here:

Best,

Unidata IDV Support

> Description of problem: Hello. I imported a GrADS file from CM1 into IDV. I 
> am interested in calculating certain cloud physics parameters in three 
> dimensions, in this case cloud liquid water content. In order to do that, one 
> needs to first calculate the temperature (in Kelvins) and density (in kg/m^3) 
> to plug into a formula for LWC. I tested out my formula for temperature 
> (which is just the standard [th*pow((prs/100000.0),(287.04/1005.7))], where 
> th= potential temperature in Kelvins and prs=pressure in Pa. It ran and gave 
> me the error that I put as the title for this email. I'm new at creating new 
> variables within IDV, and perhaps this is an easily correctable problem. If 
> there is anything else that you need to diagnose the problem, let me know.
