Fryer & Young [116
] have pointed out that current simulations are likely to be under-resolved and predict less vigorous
convection than what should happen in nature: see also [41, 70]. In general, models of convective instabilities suggest that
high resolution (above 5123 zones) across a convective cell is required to resolve convection accurately (e.g., [243]). If such
constraints from the turbulence community are correct, the current grid-based simulations in core collapse (e.g., Marek &
Janka [195
]) remain under-resolved.
