Cylinder with a pivoting pane
 

Hi everyone,

I am having some difficulty about dynamic mesh.
I started studying CFD this year and I am not used to some commands.

My project is to simulate a cylinder with a pivoting pane, where the pane would move according to the vortex generation so that the lift and drag forces reduce.

The image below ilustrate the initial condition. The flow would come from the left and then the pane would move based on the vortex generation.
The cylinder is stationary and the plane just move orthogonally to the cylinder. Both are rigid bodys.

Anyone have any ideia of how I should model it?
Should I use the UDF?

Thanks.
