Physics parameterizations for the UFS Medium Range Weather App are selected with a Suite Definition File, used by the ufs-weather-model. This is configured as part of the “comp set” for a case. The physics suite is specified with the “--compset” option to the create_newcase command.
Starting at Step #3 from the Session 1 exercises, select a different physics suite. You can query available compsets by:
cd $HOME/UFS_training/my_ufs_sandbox/cime/scripts
./query_config --compsets
./query_config --compsets
Active component: ufsatm

The Medium Range Weather App supports the two listed GFS suites, so select the GFSv16beta for this experiment:
./create_newcase --compset GFSv16beta --res C96 --case $UFS_SCRATCH/ufs-mrweather-app-workflow.c96_16beta --workflow ufs-mrweather
Change to the new case directory:
cd $UFS_SCRATCH/ufs-mrweather-app-workflow.c96_16beta
Then, continue with the instructions for Session 1: Steps #4-7.
