hi all. it seems not trivial for me to set up the proper boundary condition even for the channel flow. could anybody give me some help ? here is the way i tried, which gave me the blown solution only.

u : upper(0), lower(0), inlet(float), outlet(float) v : upper(0), lower(0), inlet(0), outlet(float) p : upper(float), lower(float), inlet(pi), outlet(po)

i am using SIMPLE algorithm, which might be the cause of this chaos. thank you.

It would help if you stated which package/software you are using.
