Witrynait was realized that a simple time marching formulation of the LB method based on an implicit Crank-Nicholson (CN) integration rule can achieve second-order time accuracy as shown by [1]. This approach, however, requires a non-linear transformation of the LB discrete distribution to an equivalent one, based on a recombination of equilibrium and ...
