MARBL ERROR

[agustin@unex_es]

I am running CESM2.1.1 with --compset BSSP585cmip6 --res f09_g17. After 77 simulated years the simulation crash with an error:

The location of the problem
(lon, lat) ( 338.955, 85.755), which is global (i,j) (149, 374)
is off the northern coast of Greenland.
This is where we have regularly seen CFL condition violation in the ocean model in warming experiments.
I see that you are running an SSP585 experiment. We do see this problem in that experiment.

Please add the following to user_nl_pop
dt_count = 48
and resubmit from the most recent restart files.

This will make the ocean model slower, so it makes sense to consider changing the PE layout.
It looks like you have less than 10 years left in the experiment.
If I were running the experiment, I wouldn't bother changing the PE layout to re-load balance.

I have changed the parameter dt_count as you suggested and it works. I can finish my simulation. Thanks
