  I am trying to simulate this, a rectangular building that will be affected by the spherical sand particle. How can I handle this solid-fluid interaction? How can I give a velocity so that the sphere moves with the flow? It would be great if anyone could help.

  You can use a Dynamic Mesh to move the sphere. You can either set a defined motion or let the movement of the sphere be dictated by the forces of the flow (Six DOF model).

  What are your modeling objectives once the sphere reaches the building?
