Hello everyone,
I am reading SIMPLE algorithm of the book An Introduction to Computational Fluid Dynamics by H K Versteeg and W Malalasekera. I am confused about hte under-relaxation of the velocity. As the book writes, CFD.png ui,J(n-1) is the velocity of previous iteration,but what about the unb? Are they the previous velocity that has been corrected? I am really confused with that, if you can give me an answer, I will be very grateful! Last edited by Harlotte; January 4, 2022 at 08:27. |
