How to change mapping file in cpl setting?

[sunweihao]

Sorry I do not find a special forum for coupler , so I sent my problem here.
I want to replace the mapping files in CESM2.0, first I change namelist in user_nl_cpl, like this:
atm2ice_fmapname='/public1/home/wgx/swh/cesm2.1.3/inputdata/cpl/gridmaps/fv0.9x1.25/map_fv09_125_TO_gx1PT_aave.220329.nc'

but when I use ./case.build , it shows ERROR:
Calling /public1/home/wgx/swh/cesm2.1.3/cime/src/drivers/mct/cime_config/buildnml
ERROR: Cannot change atm2ice_fmapname in user_nl file: set via xml variable ATM2ICE_FMAPNAME

I do not know its meaning, my question is, how can I replace mapping file?

Thanks!

Hi,

As the error message suggests, you should change the mapping file via the xmlchange command:

./xmlchange ATM2ICE_FMAPNAME=[PATH-TO-MAPPING-FILE]

Hi,

I have a question when use ./xmlchange ATM2ICE_FMAPNAME=[PATH-TO-MAPPING-FILE]
the error appears,
*** Modifying env_*.xml ***
ERROR: No variable atm2ice_fmapname found in case

Do you know how to fix it?
