woodmark75 is on a distinguished road
Hi I'm simulating a 3D wing in Fluent & am attempting to alter the Angle of Attack.
In order to save me remeshing each time (not enough experience/knowledge to use batch files), I've changed the inlet velocity to 'Components'. Then using trig (x=cos*alpha*velocity & y=sin*alpha*velocity).
The issue is that I get 'Reversed Flow' when I run the calculation?find anyt
I've searched the net to find a tutorial but can't hing detailed. Is this method correct & if so why is the flow reversing?? Thanks...
