Mechanism Submerged in Fluid

Application ID: 70251


This example illustrates the modeling of a multibody mechanism submerged in a fluid. The mechanism consists of two fins connected to a central rigid body through hinge joints. A transient fluid–structure interaction analysis is performed to simulate the swimming behavior of the mechanism, in which fin rotation generates forward motion.

The fluid–structure interaction is modeled using pairs between the fluid and solid boundaries, with bidirectional coupling between the fluid flow and the multibody dynamics of the mechanism.

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