hii,

can anybody tell me, how to do a 3d animation of vortex shedding which is generate by wind turbine during rotation.

I only manage to do a 2D contour simulation as in my photo that I attached here. I'm using the CFD-post to animate the turbine. From the Fluent, I use the 'solution data export' below the 'automatic export' section in 'calculation activities' and choose the 'velocities magnitude' as a 'quantities' . When I uploaded all the recorded file into the CFD-post environment, I managed to animate the simulation result as in the video. This way, I only get the animation in 2 dimensional contour. So, if anyone could you share with me on how to get the 3 dimensional animation of streamline or vortex or whatever. I hope that this way, my simulation will be more reasonable to be modelled in 3 dimension.

For your information my project is to analyse the vortex shedding generate by the wind turbine. Therefore, I really need to know how the 3D vortex will develop due to the turning of wind turbine.

try isosurfaces of vorticity. or lambda2, I don't remember right now how it is defined in fluent.

thank you sir, but i don't know how to record the keyframe motion...do you have any idea?
