Fluid Structure Interaction

Frequently, the flows that hydraulics engineers need to model include moving components. In FLOW-3D, the movement of objects fully coupled with fluid flow can be simulated, making it possible to improve the function of these devices quickly and reliably.

Fluid Structure Interaction Capabilities

FLOW-3D's General Moving Object model is the only one of its kind in commercial CFD software. Its fluid structure interaction capabilities allow users to model rigid body dynamics with six-degrees-of-freedom fully coupled with fluid flow. This robust model has many attributes that gives engineers a powerful and dynamic tool:
