The resolution criterion for self-gravity in AMR codes derived by Truelove et al. (1997) based on the Jeans length is a very robust one and thus quite popular. We believe that for some configurations, such as self-gravitating discs, there are reasons to supplement it in order to properly resolve gravitational instabilities and clump formation processes at reasonable computational costs.
