Can STL achieve rotational motion?

I would like to ask whether the STL of mfix can realize the rotation as shown in the figure. 1
If so, how can I implement it?

Not out of the box. For pure granular DEM, you could add a tangential velocity component along the STL. If this is TFM, you may be able to hack BC_{U,V,W}G(BCID), and BC{U,V,W}_S(BCID,M) to impose a tangential velocity, where BCID is the Boundary Condition ID, and M is the phase index. This will require some coding, and it has not been tested so I am not sure this will work.

@jeff.dietiker Thank you very much for your answer. What I use is the simulation done by PIC. I will try it according to your method.
