I am testing coupled simulation of CCSM4 with resolution T31_g37.
However, the simulation always crashes.
The simulation can run for 1-2 years, and crashes at 3 year. Then I reduce dtime, it only can run for 1 year, and crashes again. Do you have any experience about crash of simulations?
The error message always shows that Tmix did not converge. Do you know how to solve the problem? Why Tmix do not converge.
I try to reduce dtime from 1800 to 600. But it still crashes.
