Hello,I was trying to run CESM2.1 at f05_f05_mg17 resolution nudging toward MERRA2 but it stoppped when starting reading the files. Here is some info from cesm.log file:  Opened existing file /gpfs/fs1/p/cesm/chwg_dev/met_data/MERRA2/0.5x0.63/fv_0.47x0.63_nc3000_Co030_Fi 001_PF_nullRR_Nsw021_MERRA2_c180612.nc           1 Opened existing file /glade/p/cesmdata/cseg/inputdata/atm/cam/ozone_strataero/ozone_strataero_WACCM_ L70_zm5day_18500101-20150103_CMIP6ensAvg_c180923.nc           2 Opened existing file /glade/p/cesmdata/cseg/inputdata/atm/waccm/lb/LBC_1750-2015_CMIP6_GlobAnnAvg_c1 80926.nc           2 Opened existing file /gpfs/fs1/p/cesm/chwg_dev/met_data/MERRA2/0.5x0.63/2010/MERRA2_0.5x0.63_2010020 1.nc           2 WARNING: Rearr optional argument is a pio2 feature, ignored in pio1 pio_support::pio_die:: myrank=          -1 : ERROR: pionfread_mod.F90.in:         204 : NetCDF: Index exceeds dimension bound 
I didn`t understand why the value following the file is "1" or "2", and I think this caused the "Index exceeds dimension bound". Did anyone come to this kind of issue?Any help will be appreciated.

cesm2.1 is not supported at this resolution.  Index exceeds dimension bound indicates an incorrect access to the file and is not related to the number of currently open files (1 or 2)

Thank you Sir. I realized that cesm2.1 is not supported at this resolution so I interpolated the ncdata into 0.5 degree resolution and used "--run-unsupported" when I created the case.  The free-run works but the problem came out when i did nudging. Do you have any idea about this issue?
