Hi CCM users, I am running a long simulation of R15 CCM1 with an annual cycle
of specified SST's. When I get to the a step in the 17th year I am getting an
error, which is listed below.
In the 'User's guide to CCM1' I read that this error may be fixed by
increasing the number of iterations allowed for loop 324 in subroutine TSCALC.
I added the following lines to the ccm1 run script:
$I TSCALC.364
ITNUM = 200
I has also tried a plain restart and a regeneration restart. None of the
above attempts changed the error message.
I was wondering whether this error is fatal (i.e. I can not continue my run)?
I would appreciate any suggestions of what to do or where to look in order
to solve this problem.
thanks,
Uma
