Hello everybody,
I am running out of time as I realized I made a huge mistake....

I am studying a 2D airfoil (chord=2meters) and my boundary is a circle whose radius is 20 times the chord. The flow is 15m/s and I am using a pressure farfield.
I am also using the k-epsilon model but I was wrong: in the pressure farfield I chose "intensity and length scale" and I set length scale=2m (chords of the airfoil) which seems to be completely wrong.
If it is ok to use "intensity and length scale", what value should I use for length scale?
But I don't think it's ok to use it... What should I do?

My project due time is really really soon and I realize that today...
Thank you for your help!

Hi,actually giving any value into the length scale does not affect the problem at all,you might give the value "1000" and be sure that it wont matter at all.Good luck!
