Can anyone help me with the following problem?:

I have a cylinder, filled with a liquid. The fluid in the cylinder shall rotate around a HORIZONTAL axe (induced by a magnetic field).
If I move the upper cap of the cylinder with a constant velocity to the right, I get such a rotation. But it is not perfect yet. I would prefere to induce the rotation by a 'real' force IN the volume/body.

Has anyone an idea? Thank you!!!

You can upgrade the solver you are using by the implementation of a body force?
