I am not quite sure what happened in your experiment. Usually if the model becomes unstable, you will see the continuesly increase of "deriv of ps" which I did not find in your case. I know sometimes if running in 20 km, dt=30 is needed. Maybe you can do a test. But I doubt something wrong happened with your ICBC process.

Subject: [RegCNET] core dump

Dear Dr. Bi/all,

While running the model for the 20 km resolution, the model shows core dump and stops. Is there anything with dt ? I am attaching the regcm.in and regcm.out for your information. Kindly suggest...
