check_weights ERROR

[Xiaoyun W]

Hi erveryone,

I would like to try a hybrid run using CESM2.1.3. and the BHIST compset starting from the restart files of the CMIP6 historical simulations,
but when I try to run this simulation I get the following error:
#---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
ERROR: ERROR in subgridWeightsMod.F90 at line 684
check_weights ERROR: at g = 103 total PFT weight is
0.000000000000000E+000 active_only = F
check_weights ERROR: at g = 104 total PFT weight is

If you are seeing this message at the beginning of a run with
use_init_interp = .true. and init_interp_method = "use_finidat_areas",
and you are seeing weights less than 1, then a likely cause is:
For the above-mentioned grid cell(s):
The matching input grid cell had some non-zero-weight subgrid type
that is not present in memory in the new run.

I don't know how to solve this problem. Can you give me some advice?
Thanks a lot for the help!
Cheers

I had a similar issue. See here for the solution: Issues setting up hybrid run

They key is to set init_interp_method='general' within CLM_NAMELIST_OPTS in env_run.xml
