build-namelist -case?

[tannahill1@llnl_gov]

I have been using the following in some of our run scripts =>

build-namelist
-case $SUBCASE

This appears to create case_name in the namelist files. I did a search on case_name in the code to see what it is used for, and I got so many hits that it was hard for me to tell. Can someone enlighten me? Is there any place in particular that I could have looked to find this out myself?

Thanks,
John

I believe that the case_name namelist variable is only used by CAM4 as a part of the default names of output history and restart files. If you change the default filenames via the hfilename_spec namelist variable, then the "%c" part of the filename template will have the value of case_name substituted in.

The best place for information about namelist variables should be the descriptions found in the namelist documentation which is linked from the CAM4 home page: http://www.ccsm.ucar.edu/models/ccsm4.0/cam/. The current description for case_name is out of date, but I'm going to update it right now!
