 April 8, 2004, 19:23 how to setup boundary condition #1 young Guest   Posts: n/a 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.
