Hi everyone,

I want to simulate the torsion of a cylinder with OpenFOAM. (see the attached picture).
But I don't know how to set the boundary condition of the outside for the cylinder, because the direction of the stress always changes.
Does anyone have idea how to set this case?
Is it possible to set the moment as boundary condition in OpenFOAM?

Thanks a lot in advance.
