回复 32# wdlxmzd 的帖子
Two points. It's your code and it is up to you to PROVE you get the analytical solution. By the way, when we speak of the analytic solution, it is NOT normalized. We must make sure that U = G H^2/8 \nu, where G is the constant acceleration, and H = N \delta x, N is the the number of grid points across the channel. To be consistent, the LB solution should agree with the analytic one with machine accuracy. For all the claims I made, I have mathematical proofs -- I don't need
to use any program to make the point. Now you appear to have invent some thing new which I do not know, it is up to you to prove it.
Secondly, I am not laughing those "babies" as you put it. But I do either pity
those who cling to the LBGK dogma or despise them, depending on who they are.
Usually I don't fight with "babies". However, your assertiveness about your erroneous claims requires a directly response -- you have given so much misinformation through our exchanges and they cannot be ignored. Were I not involved in this discussion, I could not care less to say anything, unless I am called upon directly.
My intend to join this discussion is to exchange ideas on technical issues, and is NOT about attacking anyone. If you trace back to the all the discussions lead to where we are now, I am certainly not the one who provoke the "fight." However, I can respond to one whenever I choose to. |
