Hi all

I've a got problem with pressure on the rotor blades. There is an over-pressure at the rear side of the blades and an under-pressure on the front side of the blades. The rotor rotates as shown by the velocity vectors.

I expected exactly the opposite results and I don't know what I do wrong. Does anyone have any clue what's going on here?

Thx

Hi Volker, No idea why the so
 

Hi Volker,
No idea why the solution looks like this when the rotor rotates as the vectors show (in the opposite direction to a normal design point I would say), but could you plot the pressure on the blades, too?
