 July 3, 2010, 15:21 How to rotate a blade in fluent? #1 Member   Arash Join Date: Dec 2009 Location: Denmark Posts: 37 Rep Power: 15 Dear all, I would like to simulate a rotating blade with fluent. i was reading the manual but they explained about a 2D geometry. In 2D simulation, there is option called "axisymmetric swirl " then also in cell zone condition you can specify your rotation velocity BUT when I use 3D geometry, there is no option called "axisymetric swirl", also i cant specify my rotation velocity. could anyone help in this matter? I mean could you tell me how i can give rotational velocty to my blade and then simulate it? Thanks in advance.:-)

Hi, I too want to give rotational motion to a 3-D body in FLUENT. Can anyone tell me how to do that? In my case it's just a simple rectangular channel which has to be rotated in respect to an axis at it's origin.
