[MITgcm-support] help:the new problem i met in the MITgcm

[姊佹湅]

Dear sir:
       Thank you for your advice to my problem.But in my experiment gravity waves and non-hydrostatic effects are important.So I can't shut it down.Is there anything else I can do to expand the deltaT?And now I met a new problem.I set the deltaT=60s,and I have calculated about 30000 steps in my test,there is nothing wrong.So I started the calculating officailly,But after calculating about 140000 steps,the calculation was stopped,And the false information outputed is as follow:

So can you tell me what's the problem?Is the deltaT to long or something else?
Thank You
