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 set of verification models and associated documentation, the accuracy of electromagnetic force calculations is investigated. Using various techniques, the total force and torque on a rigid body is determined and compared to analytical models. Using fillets, advanced meshing and ... Read More
This example shows the behavior of the coupled damage-plasticity material model for concrete when subjected to different loading conditions. Read More
Focusing a laser beam onto the tip of a single mode fiber is a common way to couple light. To achieve good coupling efficiency, the spatial mode of the light field has to match the spatial mode of the fiber. In this model, we use the beam envelope method to compute a small free-space ... Read More
This example minimizes the mass of a bracket that is synchronized from Inventor® via the LiveLink™ interface. There are limits both for the lowest natural frequency, and for the maximum stress in a static load case. The size and position for a number of geometrical features is ... Read More
This tutorial model solves a two-component Schrödinger equation for the eigenstates of a simple silicon quantum dot in a uniform magnetic field, based on the paper by Jock et al. on the topic of spin-orbit qubits. The built-in domain condition Lorentz Force for the Schrödinger Equation ... Read More
The Keck Telescope is a 10 meter diameter telescope with a Ritchey-Chretien optical design. It is noted for being one of the first large optical telescopes to utilize a lightweight segmented primary mirror. This tutorial demonstrates how to use built-in polygonal mirrors from the COMSOL ...

These examples show how to model a rectangular waveguide for microwaves in 2D and 3D. A single hollow waveguide can conduct two kinds of electromagnetic waves: transversal magnetic (TM) or transversal electric (TE) waves. The models examine a TE wave that has no electric field ... Read More
A signal integrity (SI) analysis gives an overview of the quality of an electrical signal transmitted through electrical circuits, such as high-speed interconnects, cables, and printed circuit boards. The quality of the received signal can be distorted by noise from outside the circuit, ... Read More
A helical antenna has two major modes. One is normal mode and the other is axial mode. When the helical antenna is operating at the normal mode, its far-field radiation pattern is similar to the torus shaped pattern of a classic dipole antenna. At the axial mode, the helical antenna is ... Read More
Thermal energy storage units are used to accumulate thermal energy from solar, geothermal, or waste heat sources. The simplest units are built from water tanks, often found in households, where the solar energy is stored as sensible heat. The thermal capacity of these tanks can be ... Read More
