We describe a general method for modifying a given finite-difference scheme by representing the effects of the subgrid scales in terms of the resolved scales through enslaving. The new scheme is more accurate in certain parameter regimes while retaining the time-step stability of the original scheme
Here, /luJ is chosen from the condition for mJ.nJ.mum III from the relation /lu.~-ea.. All the computations are then repeated for the improved control uHI(I). The iterations are peformed until the condition I~/l is satisfied. Since (17) holds only under the assumption of infinitely small variations
