Description
I wanted to get CTSM to work with SATM, and had problems, so I tried the "S" compset to see if it would work. And it doesn't. I ran into a simple problem with buildnml, and then a problem on submission.
But, it looks like stub components are configured so that they are marked as "invalid" and CESM is setup to run without a mediator when you only have one "valid" component. But, if "CPL" is the only valid component that's a contradiction.
Here's the buildnml problem I ran into:
The problem is at the end since coupling_times doesn't have an entry for cpl_cpl_dt.

I got around that by arbitrarily getting dtime from SATM. But, then it fails at submit because minncpl is 0 and it gets a divide by zero here:
File "/glade/derecho/scratch/erik/cesm3_0_alpha07a/cime/CIME/case/case_submit.py", line 174, in _submit
case.check_case(skip_pnl=skip_pnl, chksum=chksum)

timestep = 86400 / minncpl
~~~~~~^~~~~~~~~
ZeroDivisionError: division by zero
Which I can then get past by assigning: maxcomp = "ATM", and minncpl and maxncpl to the ATM values.
It then fails at runtime with a seg-fault:
