Hi All,


I have a simple 2D cylinder with a prescribed motion of rotation around its center (constant rotational speed), AND oscillation in the vertical direction (sinusoidal motion).



If we were to have rotation only, we wouldn't need any mesh movement and rotatingWallVelocity boundary condition would work for the cylinder.



If we were to have oscillation only, we would need moving mesh with prescribed motion, and so would need movingWallVelocity.


What boundary condition should we use when we have both motions?


Other words, oscillation needs moving mesh, rotation doesn't, and so neither movingWallVelocity nor rotatingWallVelocity would work.
