Namelist Variables¶
Namelist Variable Contents¶
The following tables provide namelist.input variable options and descriptions. Not all namelist parameters require an entry for each domain, and doing so can cause an error during processing. In the tables provided, note whether variables are a “single entry” or “max_dom” entry, where “max_dom” indicates a value is expected for each domain. Additional resources for namelist descriptions and recommendations can be found in
