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.
Power inductors are a central part of many low-frequency power applications. They are, for example, used in the switched power supply for the motherboard and all other components in a computer. Computer simulations are necessary in the design of such inductors. This model calculates the ... Read More
In this example, wear of the friction material in a disc brake is studied. Quasistatic friction forces are prescribed from simple kinematic considerations. The geometry of the brake pad is continuously updated to account for the material removal due to wear following the well-known ... Read More
This models pressure-dependent heating of 4 inch wafer on unipolar electrostatic chuck. Wafer sits on top of ring with electrostatic force holdong down wafer to counter upward pressure from gas flowing in gap between wafer and chuck surface. It is a problem involving 4 coupled physics ... Read More
Model of the sound radiation from a circular duct with uniform flow. The convected acoustic problem is described using the linearized potential flow equations, solved in the frequency domain. The acoustic inlet is treated including higher order modes using the Port boundary condition and ... Read More
Heat pipes are designed to transfer heat efficiently through vaporization, mass transfer, and condensation of a working fluid. They are found in a wide variety of applications where thermal control is of importance, with cooling of electronics being a prominent example. Inside a heat ... Read More
Geothermal heating is an environmentally friendly and energy-efficient method to supply modern and well insulated houses with heat. Heat exchangers placed at a sufficient depth in the ground below the house utilize subsurface heat, where temperatures are almost constant throughout the ... Read More
In this tutorial, the acoustic properties of a wax guard are analyzed. A wax guard is a small perforated mesh used to protect the receiver (the miniature loudspeaker in a hearing aid) used for receiver-in-the-ear (RITE) or receiver-in-canal (RIC) hearing aids. Because of the very small ... Read More
This example simulates turbulent flow around a sports car traveling at a speed of 180 km/h using Large Eddy Simulations (LES). Read More
This tutorial model of a two-hot-arm thermal actuator couples three different physics phenomena: electric current conduction, heat conduction with heat generation, and structural stresses and strains due to thermal expansion. The model exists in three versions: Joule Heating of a ... Read More
A fuel cell stack operates at temperatures just below 100 °C, which means that it has to be heated at start-up. The fuel cell stack consists of unit cell of anode, membrane, and cathode connected in series through bipolar plates. This study presents a model that couples the thermal and ... Read More
