Hello, CESM team!

Recently I started BSSP126 runs with my own landtimeseries data.I checked the sum of PCT_NAT_PFT is 100, also the sum of PCT_CFT. However, my simulations stopped in 2026 with the error message as below. My version is release-2.1.3, and the resolution is 0.9x1.25. I uploaded the cism.log and lnd.log files in the attachment.

I find the same post (same post) in here. But I use the CESM2.1.3 and my error message is different: Fall_fco2_lnd gridcell index = 3850. This seem like a grid value error.

Also, I find that the minima of PCT_CROP is a Negative values very close to 0 (-3.55271368e-15).I'm not sure if this is the problem, but I'd go ahead and change the value to 0 and try to run it. Other than that, any suggestions? Or a tutorial for debug.
