"WebThis can be transformed into an expression involving the Reynolds number by making the correspondences: T=Mdt and TU=L. That is, the characteristic time for a flow is the time for fluid at velocity U to move a distance L, and the number of time steps resolving time T is M. With these relations the stability condition is then, M = 4N 2 /R. " - Fluid reynolds number
