We are currently attempting to run a multi-instance version of SP-CAM in an F_AMIP compset but using RCP 4.5 boundary condition files (grid = f19_g16). The model runs for 5 to 6 months but then crashes with an ice vertical thermo error: 125: Starting thermo, Tsn < Tmin 125: Tsn= -102.651310801067 125: Tmin= -100.000000000000 125: istep1, my_task, i, j: 5 1 34 50 125: qsn -181843378.470526 125: istep1, my_task, iblk = 5 1 2 125: Global block: 28 125: Global i and j: 161 369 125: Lat, Lon: 89.0677102300202 315.084347810016 125:(shr_sys_abort) ERROR: ice: Vertical thermo error Interestingly, we used this same simulation setup for "regular" SP-CAM and it ran without any such errors. I found this previous thread that is somewhat related: https://bb.cgd.ucar.edu/potential-temperature-problem-crashes-model-ice-component and I tried re-running the simulation with ATM_NCPL set to 96 instead of 48 in env_run.xml but I still hit the same ice vertical thermo error. Any ideas? Thanks,Mark Branson
