I have written my code in MATLAB and I need help from the forum on where things could be going wrong, my streamline plot appears not to be properly predicted and I am also not getting vortices on the corners of the cavity.
Please find code attached. Please any help with code modification will be appreciated. Thank you. Last edited by Abdels83; July 4, 2015 at 10:44. Reason: I have updated the .m file and the code is now running. I also added the streamline plot for Reynolds number of 100. |

your M-file did not run, you have some errors to correct (Lx is not defined when used, normres is not defined, etc)

if you are using primitive variables you must debug your solution (u,v,p).
The streamlines are just a post-processing that can be affected by some factors. However, the figure you attached shows a quite regular pattern for Re=100. Use a fine grid (for example 100x100) to ensure Re_h =1 and check the velocity profiles (Ghia&Ghia paper). |
