You can make NURBS and polygonal objects interact with dynamic fluids to achieve the following effects:

• The object remains stationary and the fluid collides with it behaving appropriately (collision)
• Make fluids collide with geometry
• The object moves with the force of the fluid (rigid body)
• Move geometry with the force of a fluid
• Move particles with the force of a fluid
• The object changes shape with the force of the fluid (soft body)
• Modify geometry with the force of a fluid
