Where could I download the CFD code?
 

I wrote a CFD program to calculate laminar cavity flow.
FVM+SIMPLE+staggered grids
when the reynolds number is small ( much smaller than 1), the flow seems to be no problem. Figure shows the velocity u contour at Re=0.1
but when the reynolds number become a little bigger (for example,10,or100),the flow would be quite strange. Figure shows the velocity u contour at Re=100


can anybody help me to check my codes? it is only about 400 lines.
or can anybody show me your codes? so I can check it by myself
or can anybody tell me where could I find the similar codes?

there are tons of codes available through the web. google is your friend :)
