After 830 years ERROR: bounding bracket for pH solution not found

[alexander_koch_14@ucl_ac_uk]

I'm running a long simulation with -compset B1850BPRP -res T31_gx3v7. At 839 years the model crashes with ERROR: bounding bracket for pH solution not found, which probably means that the reservoirs aren't fully spun up. The drift of about 10 ppm CO2 over the whole run lenght points in the same direction. Is there anything I can do to continue the run despite this?Many thanks,Alex

It might be an a CFL condition violation in the ocean model in warming experiments.

Try to reduce the ocean timestep.
