Hi,
@monsieuralok @oyvindseland @JorgSchwinger @JensBDebernard @tjiputra @DirkOlivie
I'm running NorESM2-LM on Betzy in emission driven mode, compset: NHISTesm
The simulation crashed after 2.5 years with the error (in the cesm log):
Ridging error: aice0 < 0
i, j, aice0: 2 9 -2.619344741106033E-008
istep1, my_task, iblk = 35970349 403 2
Global block: 2661
Global i and j: 121 360
ice: Ridging error
ERROR: ice: Ridging error

I could not find any useful information in the ice logs or any of the other logs.
I resubmitted the simulation and it has now passed the time where it previously crashed.
I have never seen this error before, so I wonder if it is related to Betzy being "unstable" or if it is something else.
Cheers,
Ada
This error was not reproduced when the simulation was resubmitted
