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

Jeffrey,

Unfortunately, you need to use some tricks because the IDV is having trouble 
dealing 
with the units.

Define this Jython function and refer to it with a formula.

def lwc(th,prs):
  lwc = noUnit(th)*pow((noUnit(prs)/100000.0),(287.04/1005.7))
  return newUnit(lwc,"lwc","g.m-3")

I describe Jython functions and formulas in this IDV video.

Let us know if you need more help.

Best,

Unidata IDV Support
