Radial Fan analysis
 

Hi everybody,

I want to simulate a radial fan geometry. I give the rotational conditions for only volume (not for the surfaces). I think there is no problem at the rotational direction but the pressure contours on the surfaces are not good.

However, I used HexCore mesh and solve it parallel.

Is there anyone can help me?

Thanks...

The blade surface should be set to moving wall with a zero rotational velocity relative to the adjacent cell zone.
