A small question,

I just performed a cylinder flow with icoFoam, but the result seems to be different from those in ferzifer's book. So i am wondering what might be wrong.

How to set upper and lower boudaries conditions?

wall or cyclic, Any ideas? Thanks a lot.

Because I am afraid if I use wall patch when Re is high, the mesh will be very expensive. I saw some paper used cyclic though in fact it is actually another problem.

Daniel
