Fan in External Analysis -> Massflow out of Fan curve-area

Hello Everyone,

 

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

 

My Problem:

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?
