[Help] Asking still about Fluid Structure Interaction
 

Hallo everybody,
I hope someone can answer my problem. I have know simulate the rotation of the mixer about 500 rpm.
the result can be seen bellow. Now because I have to solve the bending oscillation of the shaft, does anybody know how to do this? It is actually about Fluid Structure Interaction.

The problem is, that the bending oscillation really depends on the turbulent of the fluid.

I have done the tutorial guide (Vibration Pipe), which is much easier I think. Because the flow of the pipe just easily goes through the pipe. In my case, the flow of the fluid depends directly on the rotation of the mixer.

Thank you so much.
