hi deer,
I am modeling a cylinder that air flows in it. I have a pressure inlet boundary and when fluent solves this model every thing is write but there is a problem that inlet velocity vectors direction are incorrect, this vectors show the flow direction to out of cylinder!!!
where is the problem?
what should I do?
