Non Reflecting B.C.
 
Hi there; I am using CFX-11.0, for semulating transiant flow in a channel I select my outlet B.C, as constant mass flow, I wander if i will get a reflectiing wave from it? If yes. How can i define NRBC at outlet?

Hi,

NRBC is a beta feature in 11.0. If you enable Visible Beta Features in Pre through the Options panel, the options for non-reflecting boundary conditions will be available.

I did that but its available for all outlet mass and momentum option accept Mass flow rate, does that mean constant mass flow is a NRBC?
