What version of the code are you using?
ctsm5.1.dev159
Have you made any changes to files in the source tree?
Yes, I made changes in the code, and I am running with C13 on and with transient land use.
Describe every step you took leading up to the problem:
I have made changes to my code, and trying to running with C13 on and with transient land use. My case starts in 1950, runs for ~60 years but ends in 2010-05 with error message below:
car.edu 652: problem with limitations on nh4 uptake 0.000000000000000E+000
dec0268.hsn.de.hpc.ucar.edu 652: -Infinity
dec0268.hsn.de.hpc.ucar.edu 652: ENDRUN:
dec0268.hsn.de.hpc.ucar.edu 652: ERROR: too much NH4 uptake predicted by FUN
I have tried to run a C13-on, constant land cover case (with year 2000 fsurdat) with all the code change set as the same as this transient land use, and this case runs smoothly from 1950 to 2014. Here is what I added in user_nl_clm for the transient run when compared with the constant land cover run:
use_lch4=.false.
fsurdat = '/glade/p/cesmdata/cseg/inputdata/lnd/clm2/surfdata_map/release-clm5.0.18/surfdata_1.9x2.5_hist_78pfts_CMIP6_simyr1850_c190304.nc'
use_init_interp = .true.
flanduse_timeseries= '/glade/p/cesmdata/cseg/inputdata/lnd/clm2/surfdata_map/landuse.timeseries_1.9x2.5_hist_78pfts_CMIP6_simyr1850-2015_c170824.nc'
I turned ch4 off in the transient run as I met some errors in CH4 mode, but CH4 was not what I intend to study.
My code change has nothing to do with NH4 or FUN. As the case with constant land cover runs smoothly, I suspect the issue is relevant to land cover change, but I have no clue how to fix it.
The cesm.log file is too large to upload, the location is: /glade/derecho/scratch/jiamengl/C13.gm.global.lu/run/cesm.log.1087851.desched1.250705-040251
