Basic B_1850 Compilation

I'm trying to do a basic simulation with the B_1850 compset at T42 resolution. I believe everything went correctly up until I tried to run cesm_setup. My project directory had all of the appropriate .xml files and executables. Please look at the error message below and point me in the direction to solve this issue.

I have a feeling that T42 is not a supported resolution in the version of the model that you are trying to run. Hence you get:

"build-namelist - ERROR: No default value found for grid_file"

Try one of the supported resolutions, such as f09 or f19 (you'll need to find the correct abreviation for them). I hope this will get you past that error.

Thanks! I'm still working through some system-related bugs but your advice was helpful.



Hi Sara,


I have exactly same errors on T42 resolution with compset E. Have you solved this issue keeping T42?






T42 is not a supported resolution. It won't work out of the box
