This tutorial model shows how to import a 3D scanned geometry of a human head and torso and compute the head related transfer function (HRTF). The scan is imported as a .stl file and converted into a COMSOL geometry. The HRTF is computed using the reciprocity principle, locating the ... En savoir plus
A cylindrical magnet falling through a copper tube induces eddy currents on the tube walls, which in turn, create a magnetic field that opposes the magnetic field of the magnet and induces a braking force that opposes the motion of the magnet. This model computes the velocity of the ... En savoir plus
This is an example of a model of an induction motor in which eddy currents are induced in the rotor by time-harmonic currents in the stator windings and the rotor's rotation. Induced currents in the rotor interact with the magnetic field that is produced by the coils to generate the ... En savoir plus
This is a conceptual model illustrating how to couple fluid-structure interaction, heat transfer, and thermal expansion. A bimetallic strip in an air channel is heated so that it bends. After some time, an airflow with an inlet temperature which varies in time is introduced. As a ... En savoir plus
Differentially pumped vacuum systems use a small orifice or tube to connect two parts of a vacuum system that are at very different pressures. Such systems are necessary when processes run at higher pressures and are monitored by detectors that require UHV for operation. In this model, ... En savoir plus
This example demonstrates how to use a background field in a sound scattering problem. The application is an acoustic invisibility cloak made of a metamaterial. Two different types of metamaterials are used, one using an anisotropic acoustic material with varying properties and one using ... En savoir plus
A lossy ferrite circulator at 3GHz is modeled. Geometrical design parameters are varied to match the impedance for minimal reflection of the fundamental TE10 rectangular waveguide mode. En savoir plus
The bidirectional formulation of the Beam Envelopes interface can be used not only for counter-propagating wave simulations but also for waves propagating to up to two directions. In this model, an almost collimated Gaussian beam is excited at the left boundary and exhibits total ... En savoir plus
In this tutorial, the propagation of elastic waves in the ground after a seismic event is simulated using a 2D model. The effect of the ground surface topology on the wave propagation is illustrated when an ideal half space is modified with the presence of a small mountain. The model is ... En savoir plus
These examples demonstrate how to compute the total reflection, transmission, and absorption of light when a plane wave, at optical wavelengths, is incident upon a dielectric slab with a thin metal coating. Three examples are included that show: An optically flat slab A slab with a ... En savoir plus
