... second-order upwind differencing are discussed and compared in [2-3] . Second-Order Accuracy in Time When using a method that is first-order accurate in time but second-order accurate in space, ... v∆t significantly smaller than ∆x to achieve desired accuracy, say, by at least a factor of 5. Thus the Courant condition is not actually the limiting factor with such schemes in practice. However, ....
