forrtl: error (73): floating divide by zero

[shiwansha]

I have build a default cam with compset (F_1850-PDAY_CAM5) with default SST and SIC. I have started the model from 1950. It run till 1953-09-07 and after this date model crashed. Please find the last few lines of error in cesm.log file mentioned below. Please see the README.case file to know the detail about the case (attached to this request). I have also attached the log file of all components.

Hi, I have removed some of the repetitive lines in cesm log file because it was too large to upload.

Thanks

Hi,

Looking at your cesm.log* file, the error is a "floating divide by zero" on line 4846 of uwshcu.F90. So that's a good place to start. I don't know what version of CAM/CESM you are using so I don't know exactly what's happening at that line.

If you're still having trouble, please provide the version of CESM and/or CAM you are using.

Courtney

Dear Courtney,

I am using CESM1.2.2 and CAM5.

This is the compset I have used.

PIPD_CAM5_CLM40%SP_CICE%PRES_DOCN%DOM_RTM_SGLC_SWAV

Thanks
-Shiwansha.

Hi Shiwansha,

We no longer support that version of CESM - can you update to a later version? I would recommend GitHub - ESCOMP/CESM at release-cesm2.2.2
