Fluid Structure Interaction for Water & Environmental Applications

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:

Users can evaluate the motion of multiple objects.
There are no limitations on the geometry or range of motion.
Objects can be allowed to move freely, or the user can prescribe the motion.
Specified time-dependent thrust forces and torques can be applied to the objects.
The range of motions includes motion around a fixed axis or point.

Floating logs collide with each other and with the wall, step and bottom of the channel.
