According to the documentation for DRV namelist options, there is supposed to be an ORBITAL_MODE in env_run.xml. I'd like to use that to set a run to use the "fixed_parameters" option, but I don't see ORBITAL_MODE in env_run.xml. Using CESM1_2_0 on Yellowstone. Tried a B and an F compset, just to make sure I wasn't missing something.Is there a "right way" to set orb_mode='fixed_parameters' ? Should it go in user_nl_cam since there is no user_nl_drv?
