Mechanism Submerged in Fluid

Application ID: 70251

This example illustrates the modeling of a multibody mechanism submerged in fluid. The mechanism considered here consists of two fins connected to a central rigid body through hinge joints. A transient fluid-structure interaction problem is solved to simulate the swimming behavior where fin rotation generates a forward velocity in the mechanism.

The fluid-structure interaction is modeled on the pairs between the fluid and solid boundaries. A bidirectional coupling is assumed between fluid flow and the multibody model of the mechanism.

This model example illustrates applications of this type that would nominally be built using the following products:
