Vibrations in a Milk Container

This example illustrates a multiphysics application that involves a fluid-structure interaction. It simulates a filled milk container on a conveyor belt, which starts moving.

The methodology presented here defines two problems, one for the container walls and one for the fluid. The two problems are subsequently merged into one problem using a special interface condition that imposes continuous normal displacements and normal forces across the interface boundary. The model is set-up in COMSOL Multiphysics' using equation-based modeling.

The deformed shape shows the displacement of the milk container due to the fluid forces. Surface color indicates the horizontal displacement.
