Hi CESM community,
I aim to run an experiment for 2015–2035 under the SSP245 scenario but reduce computational cost by switching from BWSSP245 (fully coupled ocean) to FWSSP245 (data ocean mode, DOCN%DOM).
I am using CESM2.1.5 and attempting to modify an existing COMPSET (BWSSP245) to create a custom FWSSP245 configuration. The key changes include:
Component Switches:
Ocean: From POP2%ECO%NDEP (active ocean) → DOCN%DOM (data ocean)
Sea Ice: From CICE → CICE%PRES (prescribed)
Method : Direct COMPSET Longname Modification
Edited BWSSP245's longname:

my codes（eg:Edited FWHIST's longname）:
COMPSET="SSP245_CAM60%WCTS_CLM50%SP_CICE%PRES_DOCN%DOM_MOSART_CISM2%NOEVOLVE_SWAV"
RES="f09_g17"
MACH="huan"
./create_newcase --case $CASE_NAME --res $RES --compset $COMPSET --mach $MACH --run-unsupported
cd $CASE_NAME
./xmlchange NTASKS=-20
./xmlchange NTASKS_WAV=600
./case.setup
./xmlchange STOP_OPTION="nmonths"
./xmlchange STOP_N=3
./xmlchange REST_OPTION="nmonths"
./xmlchange REST_N=1
./case.build --skip-provenance-check
./case.submit
Current Issue
After running ./case.submit, I encounter the following error:（See detailed error report below.）
ERROR: Could not find all inputdata on any server
Questions
Configuration Check:
Do I need to modify user_nl_docn to specify the ocean input data path even after changing the COMPSET?
Data Source Request:
If additional input files are required, could you provide downloadable data links (e.g., official CESM repositories or CMIP6 datasets)?
I will be very grateful for any response or answer.
Thanks in advance!
