Issue with evolving Antarctic Ice Sheet set up

[gunterl]

I am trying to set up a case (for testing purposes) with an evolving Antarctic ice sheet. For this I am using the development CESM tag cesm2_3_beta11. I am setting up a case using (following the documentation): ./create_newcase --case /glade/work/gunterl/cesmcases/CESM3_test/bgag.e21.B1850G.f19_g17.CESM3_test_ais --compset 1850_CAM60_CLM50%BGC-CROP_CICE_POP2%ECO_MOSART_CISM2%AIS-EVOLVE_WW3_BGC%BDRD --res f19_g17 --project P93300601 --run-unsupported

When I go into my case directory, GLC_GRID is set to gris4 (instead of ais8) and GLC_NX and GLC_NY have the dimensions associated with the Greenland grid as well.

Running ./preview_namelist leads to the following error (which is coherent with the settings): _ERROR: Inconsistency between compset and grid: ais included in compset, so expect one grid starting with that name, but found 0 grids with that name in GLCGRID gris4

How can we fix this problem?

You need to specify a grid that includes Antarctica instead of Greenland in your --res argument. This is set up out-of-the-box for f09_g17: you can use f09_g17_ais8. I don't think there's an equivalent grid alias for f19_g17_ais8, but you can use the grid long name or add a grid alias for that - see:

I think I have answered the question here, so closing. Feel free to reopen if there's still an issue.
