I'm trying to run a quadruple CO2 simulation in SD-WACCM-X by performing a branch run where I quadruple the CO2 in the lower boundary as well as in the restart file that the run is initializing off of.
To do this, I first performed a run with standard CO2 for one month, then I did a second (branch) run that initialized off of the restart files from that first run, except I multiplied the variable ‘CO2’ from the cam.r restart file by 4, and also multiplied the lower boundary CO2 variable ‘CO2_LBC’ by 4 in the flbc_file. Aside from these changes, the files were not modified.
However, when I try to actually run the simulation, I get the following error: “GHP7 NOT CONVERGING FOR PRESS” and “nlte_fomichev_calc: CO2 has exceeded the limit: nstep,i,k,press(Pa),lon,lat,vco” at many different locations, then the run fails/aborts. The error file is attached.
I have attached my user_nl_cam, env_run.xml files, and the error file. I also attached the python scripts where I created the new versions of the restart and lower boundary files so you can see exactly what I am doing.
The problem must be related to the restart file, because I was able to perform a similar run by only modifying the LBC file and there were no errors.
The run directory is on derecho / glade here: /glade/u/home/bmartinez/f.e21.FXSD.f09_f09_mg17.CO2x4_experiment and here
/glade/derecho/scratch/bmartinez/f.e21.FXSD.f09_f09_mg17.CO2x4_experiment/run
Do you know how I can get around this issue?
