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 tutorial, a PM motor with 10 rotor poles and 12 stator slots is modeled in 2D, to capture the torque ripple over an electrical period and map the volumetric loss density in the rotor and stator iron. Read More
Reflective mufflers are best suited for the low-frequency range where only plane waves can propagate in the system, while dissipative mufflers with fibers are efficient in the mid- to high-frequency range. Dissipative mufflers based on flow losses, on the other hand, also work at low ... Read More
This tutorial demonstrates a structural analysis of a simple telescope. The deformation of the telescope structure under gravity is examined and the effect on image quality is demonstrated. Read More
This example illustrates the use of the Maxwell-Stefan diffusion model available with the Transport of Concentrated Species interface. It models multicomponent gas-phase diffusion in a Stefan tube in 1D. In this case, it is a liquid mixture of acetone and methanol that evaporates into ... Read More
An isothermal single particle model formulation for a lithium-ion battery is presented in this work. The single particle model is a simplification of the 1D formulation for a lithium-ion battery along with a few assumptions. The model is typically valid for low-medium current scenarios. ...

This example shows how to implement a stress dependent material model. The Young's modulus changes based on the stress value. Read More
The bracket models are used as an introduction to structural mechanics modeling with the Structural Mechanics Module. The following features are introduced: The fundamentals: static linear analysis Parametric study Including initial strain Modeling thermal expansion Adding a rigid ... Read More
Lead-acid batteries are widely used as starting batteries for various traction applications such as cars and trucks and so forth. The reason for this is the fairly low cost in combination with the performance robustness for a broad range of operating conditions. However, one drawback of ... Read More
Zinc-Silver oxide (Zn-AgO) batteries are used in different industries due to their high capacity per unit weight. In this work, discharge of a Zn-AgO battery is simulated using the Battery with Binary Electrolyte interface. The electrochemical reactions in the positive and negative ... Read More
This model is used on "Heat Transfer with Radiation in Participating Media and the Discrete Ordinates Method" to compare quadrature sets used in the method of discrete ordinates. The reference analytical solution of incident irradiation is obtained with 256 discrete directions. Errors in ... Read More
