Usman Guest Posts: n/a	Hi guys, i am simulating a flow on a backward facing step. I want to impose fully developed flow at the inlet in a rectangular duct. In CFX tutorials (i think its tutorial 9) where it tells us how to write an expression for a circular pipe. But can i use that expression for a rectangular duct?? I think i cant use it! How can i then write an expression for a fully developed flow at the inlet of rectangular duct.
