Error: CAM_CICE_DOCN%SOM

Hi,

I would like to run unsupported SOM with sea ice. All things I changed in the model are as follows:

Compset (unsupported): 2000_CAM60_SLND_CICE_DOCN%SOM_SROF_SGLC_SWAV
Grid: f19_g16

user_nl_cam:
avgflag_pertape = 'A','A'
fexcl1 = ''
fincl2 = 'RELHUM','RHO_CLUBB','PS','PSL','Q','T','SST','PRECC','PRECL','PRECT','U','V','Z3','OMEGA','QFLX','FLNS','FLNT','FSNS','FSNT','LWCF','CLOUD'
mfilt = 12,365
nhtfrq = 0,-24

user_nl_cice:
kdyn = 1
kitd = 1
ktherm = 2
ice_ic = '.../my_cesm_sandbox/cesm_input_datasets/ice/cice/b.e15.B1850G.f09_g16.pi_control.25.cice.r.0041-01-01-00000.nc'
grid_file = '.../my_cesm_sandbox/cesm_input_datasets/ocn/pop/gx1v6/grid/horiz_grid_20010402.ieeer8'
kmt_file = '.../huangyy/my_cesm_sandbox/cesm_input_datasets/ocn/pop/gx1v6/grid/topography_20090204.ieeei4'
grid_format = 'bin'
grid_type = 'displaced_pole'

env_run.xml:
<entry id="DOCN_SOM_FILENAME" value="pop_frc.b.c40.B1850CN.f19_g16.100105.nc">

I can setup, build, and submit the case successfully. The outputs included the CAM history files (within a month) and log files of all components, which seemed to run normally. After it ran for a while, it stopped. The error in CESM.log file is as follows:

I browsed the Forum and found a solution. So I added some changes in the CAM user_nl_cam:

dtime = 1200
fv_nspltvrm = 4
fv_nsplit = 16
fv_nspltrac = 4

This time, it could run longer (over a month) and have a sea ice history file. But it still stopped finally with these errors:

20: Vertical integral of xm is zero;mfl will remove spike at top of domain,
20: but it will not conserve xm.
23: Lagrangian levels are crossing 9.999999999999999E-012
23: Run will ABORT!
23: Suggest to increase NSPLTVRM

The log files are packaged in the attachment. I have no idea to solve these problems. Actually, I have met these problems when I tried the f09_g16 grid and the thermo_only sea ice cases. Does anyone know the solution? Any suggestions are appreciated.

Thank you so much!

Best regards,
Rose
