Dear CESM experts, Having succesfully run CLM in offline mode with the user compset 1850_DATM%CRU_CLM45%CN-CROP_SICE_SOCN_RTM_SGLC_SWAV, I would now like to start a hydrid run. But because the simulations are really slow I would like to increase the default 30min time step to 2h. I was hoping to achieve this by inserting the following commands in my runscript: # impose 2-h time step (instead of default 30min), i.e. couple atmosphere and land 12 times per day
./xmlchange -file env_run.xml -id ATM_NCPL -val "12"
./xmlchange -file env_run.xml -id ROF_NCPL -val "12"
Judging from this presentation (slide 40-42) this is the way to go. Yet when I implement this change I get the following error message in my cesm.log file:--------------------------------------------------------------------------------------------------------------------------------seq_flds_mod: seq_flds_x2w_states=
Sa_u:Sa_v:Sa_tbot:Si_ifrac:So_t:So_u:So_v:So_bldepth
seq_flds_mod: seq_flds_x2w_fluxes=
(shr_sys_abort) ERROR: (shr_stream_readTCoord) ERROR: nf90_get_att units
(shr_sys_abort) WARNING: calling shr_mpi_abort() and stopping
-------------------------------------------------------------------------------------------------------------------------------- The error does not occur when I stick to the default 30min time step. The error seems to occur during initialisation, and seems to suggest that the time step is somehow included in a restart file? Any idea what I'm missing here? Many thanks in advance for your much-appreciated help! Best wishes,Wim
