I have read the unit choice of Lattice Boltzmann simulation and refer to your suggestions, that maybe the reason why I confused. rnrnThe Reynolds number is not exactly the physical system Reynolds number only depend on the reference you chose.Am I right now?rnAnswer: That is right! [Mathias]rnrnmany thanks rnrnJepson
