stream-function vorticity formulation

Hi all,
I am trying to solve the lid-driven cavity flow problem in the stream-function/vorticity formulation. I think I have correctly applied the bc's. I am using second order central differencing scheme, with explicit time marching for the vorticity equation, and TDMA to solve the possion equation for stream function. I am getting some weird results, as can be seen in the vorticity contours here. any ideas as to what i could be doing wrong? |
