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.
In this model, an axial field magnetic gear with a gear ratio of 5:2 is modeled. Both the high-speed and low-speed rotors consist of permanent magnets and back iron. The low-speed rotor consists of five pole pairs, while the high-speed rotor consists of two pole pairs and the stationary ... Read More
This example exemplifies how curve fitting can be performed in COMSOL Multiphysics®, and how this can be applied to your modeling. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Curve Fitting of Experimental Data with COMSOL ... Read More
This model illustrates the working principle of a passive electrodynamic bearing. An electrically conducting rotor rotating in a magnetic field produced by a permanent magnets induces eddy currents on the conducting rotor. The eddy currents, in turn, produce a magnetic field that opposes ... Read More
This model analyzes Joule heating and thermal expansion in a bond wire in an LED. Its purpose is to estimate the temperature increase and the resulting mechanical stresses in the bond wire due to thermal expansion. The magnitude of these stresses can be used to assess the risk of fatigue ... Read More
The model of 1D Dielectric Barrier Discharge (DBD) has been recomputed with the three different kinds of electron energy distribution functions (EEDFs): The Maxwellian function The Druyvesteyn function The computed EEDF based on the Boltzmann Equation, Two-Term Approximation ... Read More
In this example, the natural frequencies of a double hat beam are studied. The beam is made of two thin steel plates, joined together by spot welds along the flanges. The Spot Welds feature sets up multiple mesh-independent connections between the shells. Read More
This example exemplifies how to model applications using the Events Interface where a thermostat is simulated. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Implementing a Thermostat with the Events Interface". Read More
This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Solid Edge® via the LiveLink™ interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz. Read More
This model file was used for creating the plots featured in the blog post "How to Model Ion-Exchange Membranes and Donnan Potentials". Read More
In this example, a heat transfer model of a fiber composite's unit cell is analyzed with the Cell Periodicity feature. The homogenized thermal conductivity, density and heat capacity of a composite material are computed based on the individual properties of fiber and matrix. A comparison ... Read More
