CESM 1_2_0 rtm.buildnml.csh for branch run

[zwang19@masonlive_gmu_edu]

Hi,

I was trying to start a branch run in cesm 1_2_0.
When setting up cesm_setup, there was an error occurred:

--------------------------
ERROR(Build::Namelist::_parse_next): expect a equal '=' sign instead got: .rtm.r.0110-01-05-00000.nc
ERROR: rtm.buildnml.csh failed
--------------------------

So I checked the $CASEROOT/Buildconf/rtm.buildnml.csh and found the below paragraph:
--------------------------
if ($RUN_TYPE == 'branch') then
set nrevsn_rtm = "${RUN_REFCASE}.rtm${inst_string}.r.${RUN_REFDATE}-${RUN_REFTOD}.nc"
if( -e "$RUNDIR/$nrevsn_rtm") then
set nrevsn_rtm = "nrevsn_rtm='$nrevsn_rtm'"
else
set nrevsn_rtm = "${RUN_REFCASE}.rtm.r.${RUN_REFDATE}-${RUN_REFTOD}.nc" #####
endif
if ($GET_REFCASE == 'TRUE') then
set refdir = "$DIN_LOC_ROOT/ccsm4_init/$RUN_REFCASE/$RUN_REFDATE"
ls $refdir/*rtm* >& /dev/null
if ( $status != 0 ) then
set nrevsn_rtm = "nrevsn_rtm ='${RUN_REFCASE}.clm2.r.${RUN_REFDATE}-${RUN_REFTOD}.nc'"
endif
endif
endif
--------------------------
I then edited line ##### into:
--------------------------
set nrevsn_rtm = "nrevsn_rtm='${RUN_REFCASE}.rtm.r.${RUN_REFDATE}-${RUN_REFTOD}.nc'"
--------------------------
after that the cesm_setup could complete without an error!

I wondered if the bug only happens to me or not, since I searched the forum and didn't find people reporting the issue.

Best,
Zaiyu

I hit this bug a while ago, and I worked around it it the same way that you did. I believe that the RTM development version is now fixed, so that will make it into next year's release of CESM.

I also ran into this same bug when starting a branch run with CESM1_3_beta01, and fixed in the same way.
