[Wrf-users] Issues using lat-lon map_proj in ARW

I am attempting to run a simulation in WRF-ARW using a lat-lon map

WPS runs fine.  DX and DX are set to 0.018, and MAP_PROJ is set to
lat-lon in the namelist.wps

Upon running REAL.EXE, I received the following error...

"DX and DY do not match from the namelist and the input file"

I have tried two different settings for DX and DY in namelist.input;

DX and DY = 0.018 (degrees)


DX and DY = 2000  (m)

Both give me the same error.  I am out of ideas on getting this to
work.  Any help would be appreciated.
