configuration issue (cesm_setup) in ice files?

Hi CESM helpers! I am having a problem setting up a basic CESM run that I think is due to the cice namelist not being created.  When running cesm_setup, I get this output: Macros script already created ...skipping
Machine/Decomp/Pes configuration has already been done ...skipping

Bill,You should know better than to use prescribed ice. ;) There is a bug in the inputdata check that doesn't retrieve all of the data for the CICE model. If you edit $CODEROOT/models/ice/cice/bld/build-namelist and delete the following two lines from this script, it should work. You can also manually check the ice_in file and svn export the relevant files.Dave===================================================================--- build-namelist    (revision 46739)+++ build-namelist    (working copy) @@ -823,8 +827,6 @@         }         }     }-    close OUTFILE if defined $inputdata_rootdir;-    return 0 if defined $inputdata_rootdir;     } } 
Hi David,    Today I've met the same problem as Bill's. I deleted the two lines as you told, but cesm_setup still doesn't work. And check_inputdata can not found ice_in files.    The create_newcase process is :-user_compset 2000_CAM5_SLND_CICE_DOCN%SOM_SROF_SGLC_SWAV -res f19_f19    Thanks for help. -------------------------------------    CAM writing dry deposition namelist to drv_flds_in CAM writing namelist to atm_in CICE configure done.build-namelist - ERROR: No default value found for grid_fileuser defined attributes:Died at /work/zhxc_work/cesm1_2_1/models/ice/cice/bld/build-namelist line 708.ERROR: cice.buildnml.csh failedERROR: /work/zhxc_work/cesm1_2_1/scripts/f19f19FSOMI/preview_namelists failed: 25344

There are several issues here. First, this is not a supported compset and you need to work this out on your own. Second, this grid combination f19_f19 is not supported for SOM mode. Third, you need to read the FAQ for the SOM at:
