This paper shows how the circular motion of a rotor with permanent magnets generates an induced EMF in a stator winding. The generated voltage is calculated with moving mesh in COMSOL Multiphysics as a function of time during the rotation. The model also shows the influence on the voltage from material parameters, rotation velocity, and number of turns in the winding. © (2012) Trans Tech Publications, Switzerland.

This paper demonstrates techniques for modeling fluid-structure interactions with moving mesh in COMSOL Multiphysics. It illustrates how fluid flow can deform surrounding structures and how to solve for the flow in a continuously deforming geometry using the arbitrary Lagrangian-Eulerian (ALE) technique. The ALE method handles the dynamics of the deforming geometry and the moving boundaries with a moving grid. © (2011) Trans Tech Publications, Switzerland.

This paper shows how to model two immiscible fluids, tracking the fluid-fluid interface with the level set method. An oil bubble rises through water and merges with oil already residing at the top of the container. The Level Set application mode finds the fluid interface by tracing the isolines of the level set function. © (2011) Trans Tech Publications, Switzerland.
