The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
The thermal effects of a laser beam incident on a Semiconductor Saturable Absorber Mirror (SESAM) are simulated under a range of incident beam powers. This is done in two steps. The first study simulates the multiphysics combination of the saturated absorption of the beam on a SESAM, ... Read More
This single-phase induction motor model is used to compare with Testing Electromagnetic Analysis Method (TEAM) workshop problem 30. The Magnetic Fields physics interface is used to model the motor in the frequency domain at 60 Hz. The Velocity (Lorentz Term) feature is used to model the ... Read More
The electrical insulation strength of gases is generally much lower than that of solids. Under normal operating conditions, electrical discharges—known as partial discharges—can occur in voids or cracks within a solid dielectric. This model simulates partial discharges in a spherical ... Read More
This model simulates a holographic page data storage system. The studies include the recording and retrieval processes. The object beam encrypting 8-bit data is focused into a holographic material by a Fourier lens (Fourier transformation). In the recording process, the object beam ... Read More
An interesting question was raised in the 1950s by the mathematician Ernst Straus that, in an arbitrarily shaped empty room with side walls made of perfect mirrors, will a point light source always illuminate the whole room? This question was answered by the Nobel Prize-winning ... Read More
Many robot vacuum cleaners nowadays are equipped with lidar for spatial mapping in order to design an optimal cleaning path and navigate in a room without bumping into obstacles. This model simulates the lidar of a robot vacuum cleaner and how it maps out the shape of the room using ... Read More
A magnetic diaphragm is a flexible, thin structure that interacts with magnetic fields to perform mechanical or sensing functions. When subjected to an external magnetic field, the diaphragm deforms due to magnetomechanical interactions, converting magnetic energy into mechanical ... Read More
This model demonstrates the simulation of surface dielectric barrier discharges (DBDs) using the Electric Discharge interface. The formulation incorporates a comprehensive set of physical processes, including charge transport, impact ionization, electron attachment, recombination, and ... Read More
This model simulates a beam of light being split into components of different frequencies when passing through a medium where the refractive index depends on frequency. COMSOL-wise, the model showcases two important technical aspects: A user-defined implementation of the frequency ... Read More
This model demonstrates how to find the optimal size and position of a water pipe in an air chamber, so that the energy absorption in the water is maximized. The objective is implemented as a constraint, so that the optimization terminates, when the desired performance is achieved. Read More
