Dear Forum, I encounter the following error message when running the E-compset with prescribed SOM data file from a coupled run (ccsm log file):Repeat ridging, niter = 12
Repeat ridging, niter = 20

Exceeded max number of ridging iterations
max = 20

Any suggestions what might cause this problem and where to start debugging? Thanks!

I also encountered similar problems when I add a new atm component，please tell me how to solve？

Sorry for not seeing this sooner. This is likely because you are getting excessive winds. Try writing out every timestep coupler history to see where the problem is originating. You might be able to increase ATM_NCPL/ICE_NCPL to alleviate the problem.Dave
