velocity slip at wall -- CFD Online Discussion Forums

SA Guest Posts: n/a	I am trying to simulate flow in a microchannel. I want to specify slip velocity at the wall of a microchannel. The equation is something like: U@wall=Constt.*(du/dy)@wall How can I get the value of du/dy? What DEFINE MACRO should be used for this problem? Thank you.
