I have been reading a paper which says that "to ensure similar forcing on all simulations the 64^3 runs are forced on a 32^3 grid; this is non-trivial since the flow is sensitive to energy addition and its distribution. " (An comparative study of sgs models in homogenous turbulence , Fureby et al, 1997. ). Can anyone explain what this means?
