Outlet Orientation Issue
I am working on modeling a wind tunnel that I am designing. I just recently began with Caedium, but I am having issues with a simple preliminary model of the test section with air flowing in through a circular hole face in the wall (where the nozzle would connect, but without the nozzle) and out through a large circular collector. I am just trying to do flow visualization using particle targets.
My issue lies in the outlet. As the air flow approaches the outlet, it goes back towards the inlet as though it is being pushed backwards. I am wondering if the outlet is operating with the incorrect normal orientation. Is there a way to change the direction of positive normal on an outlet?
Advice is much appreciated! Thanks!
