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.
This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize geometry between the AutoCAD® software and the COMSOL Multiphysics® software, how to modify the geometry from COMSOL Multiphysics®, and how to run a geometric parametric ... Read More
In this model, we show how to model Seebeck effect which works as a thermoelectric generator. Seebeck effect is a phenomena where the difference in temperature of a material leads to a potential difference. The potential drawn in this model was compared with the paper by Jaegle (Example ...

This model uses the Optimization interface to solve the inverse problem for determining the spatially variable hydraulic conductivity on a discretized quadratic grid from a number of aquifer pump tests. Because the number of observations is smaller than the number of unknown parameters, ... Read More
This model computes the transmission probability through an s-bend geometry using both the angular coefficient method available in the Free Molecular Flow interface and a Monte Carlo method using the Mathematical Particle Tracing interface. The computed transmission probability by the ... Read More
This model computes the transmission probability through an RF coupler using both the angular coefficient method available in the Free Molecular Flow interface and a Monte Carlo method using the Mathematical Particle Tracing interface. The computed transmission probability determined by ... Read More
This example shows how to model a FinFET in 3D. The I-V characteristics of the device are simulated. First, the gate voltage is swept to obtain the drain current versus gate voltage plot. Then, the drain current versus drain voltage characteristics are computed for fixed gate voltages. Read More
This model simulates the propagation of a double-headed streamer in nitrogen at atmospheric pressure. Initially, electron-positive ion clusters were introduced between two parallel electrodes, subjecting the gas to a strong background electric field of 52 kV/cm. Subsequently, both the ... Read More
This is a model of an RF waveguide bend with a dielectric block inside. There are electromagnetic losses in the block as well as on the waveguide walls which cause the assembly to heat up over time. The material properties of the block are functions of temperature. The transient thermal ... Read More
This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Inventor® 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
