Problem with Lid driven cavity collocated grid SIMPLE
1 Attachment(s)
Hello everyone,
I am trying to write code about 2D Lid driven cavity in collocated grid with SIMPLE algorithm in MATLAB. I have tried to write code in staggered grid with SIMPLE and it is sucessful. But in the collocated, I run the code and the values seem not to be convergent. I discretize the governing equations with FVM and interpolate using the first-order upwind method. I follow the steps in the book about the collocated grid SIMPLE but it doesn't work. I also check my code with the flow chart by @Freewill1 Link:https://www.cfd-online.com/Forums/ma...ated-grid.html. It seems my code is logical correct but it can't run well. I hope someone can take a look at my code and help me point out my errors. Thank you! |
