topography not supported for CESM2.0 Spectral Element dycore

[liangch@illinois_edu]

Hi CESM users,

I am trying to run CESM2 with CAM-SE (--compset F2000climo --res ne16_g17). When I was checking the namelists by run .preview_namelists, I got this error:

out=CAM build-namelist - ERROR: No default value found for bnd_topo

So I added the topography file, but got the following error:
 
err=CAM build-namelist - ERROR: Use of topography not currently supported with SE dycore
 
Then I saw this in cesm/components/cam/bld/build-namelist
 
if ($dyn =~ /se/) {
 
    ## topography not supported for CESM2.0
    if (!defined $use_topo_file or ($use_topo_file =~ m/$TRUE/io)) {
      die "$ProgName - ERROR: Use of topography not currently supported with SE dycoren";
    }

Does anyone know how to fix this problem?
 
 
Thank you!

The version of SE in the current cesm2.1 release is not officially supported, but it can be run with the simple model configurations (no topography).  More complete support for the SE dycore is expected in a future CESM2 release.

Dear Eaton,

have this problem fixed in the new CESM version? I meet the same problem when I build the simulation with FWHIST_BGC component. However, I found Gettelman (2018) mentioned the CAM6 is work with full physics. Could you help me? Thank you very much.

Hi All,

This question has been answered here:

Please note that the citation referenced above used model code which should be available in CESM2.2, although that particular version has not been released yet.
