question of setting pressure on boundary
 
Hello
I want to use CFX to simulate water flowing in a duct. One side of this duct is connected with a very larger top-openned reservoir and the other side is applied with a negtive pressure [like vacuum pump] to suck water out. What kinds of pressure type should I define in inlet side at reservoir top face and outlet side ?
Thank you !!

A total pressure outlet and a static pressure inlet at the reservoir should do it.
