UPP for WRF-NMM

[lliu]

What do I use to post process the wrf output data from WRF-NMM to GRIB data that can be read by GrADS?
I tried UPP, but it gave me error message, complaining about the unknown grid. Please help!

Please any one help me with UPP on wrf-nmm output data? The user guide doesn't cover wrf-nmm.
