Questions about clm50cn!!

[XinhaoSuo]

Hi,
I really don't know where I have a problem here, I just want to run an I2000CLM50CN model, so just do some basic Settings.
./xmlchange STOP_OPTION=nyears,STOP_N=170,NTASKS=164
./case.setup
./case.build
./case.submit

However, I never see the growth of vegetation.
In the result, TOTSOMC only had 20 Pgc and decreased to 5Pgc, TLAI was 0.25 in the first year and then approached 0.
Meanwhile, I ran a BGC model for comparison, and its' TOTSOMC was 2000pgc.
In my opinion, both TOTSOMC and TLAI are one of the important indicators to test the quality of vegetation, but it is obvious that my CLMCN model cannot do this.

Can someone give me some help?

As noted in this post, CLM5 with CN is not scientifically supported:

Question about clm-cn

Hi, I tried to run I2000CLM50CN composet for ten model years without making any modifications. However, when I checked the output TLAI or GPP, I found that its value was normal in the first year, but it began to decline rapidly in the second year and approached 0. I understood that this meant...
