CLM_FORCE_COLDSTART settings

[Jie Hsu]

I have changed the command below:
./xmlchange CLM_FORCE_COLDSTART = -ignore_warnings on

but it seems not to work..., the error messages...

WARNING: CLM is starting up from a cold state
ERROR: Command /home/d07229003/cesm2_3_alpha17b/components/clm/bld/build-namelist failed rc=255
out=
err=Warning : CLM build-namelist::CLMBuildNamelist::setup_logic_initial_conditions() : setting finidat (either expl icitly in your user_nl_clm or by doing a hybrid or branch RUN_TYPE)
is incomptable with using a cold start (by setting CLM_FORCE_COLDSTART=on).
-- Add -ignore_warnings option to CLM_BLDNML_OPTS to ignore this warning

can anyone help to answer these settings? Thank you.

Moving this to the CLM forum.

It looks like you are mixing the two XML settings.

First to make it do a cold-start

./xmlchange CLM_FORCE_COLDSTART=on

Then if you want to ignore warnings do...

./xmlchange CLM_BLDNML_OPTS='-ignore_warnings on'

Do you really want to do a coldstart though? Initial conditions reasonably close that can be interpolated from are usually provided. A coldstart means it uses isometric soil temperatures and will need at least decades if not centuries to Millenia of simulation time to get spunup.
