i am doing an external Analysis with an fan in the beginning of a tunnel.
In the end of the tunnel there is a body with an internal heat source.
I did set the fan as an "extern fan (inlet)" -> Warning
Then I tried "intern fan" -> Warning
There is always a warning which says like "Mass flow out of Fan curve-area"
When I do check the surface volume flow on the fan surface it really says that
there is more volume flow (like 5% more than at the 0 Pa fan curve).
Can anyone help me?
