I try to run the RegCM4.1 model but stopped at the step of “test
simulation”. I wanted to create the DOMAIN file using terrain, and got
errors

>./Bin/terrain test_001.in

error as followed:

Determined Grid coordinate range

 Opening $REGCM_GLOBEDAT/SURFACE/GTOPO_DEM_30s.nc

 NetCDF library error.

 No such file or directory
