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 is a demo model to show how to model connections in a mechanical system using Multibody Dynamics interface. In this model, pantograph mechanism is modeled. The purpose of this mechanism is to produce an identical, either enlarged or miniaturized, copy of an existing drawing. Read More
A demultiplexer is a device that directs different frequency bands to different outputs. In this tutorial model, we will design a demultiplexer by performing shape optimization on all initial circular boundaries in a sonic crystal (phononic crystal) configuration. The model uses shape ... Read More
Cryer's problem is a three-dimensional consolidation benchmark. A porous sphere is subjected to a uniform boundary pressure. The pore pressure at the center of the sphere rises due to the Mandel-Cryer effect that is captured by a two-way coupling between Darcy's law and solid mechanics. Read More
This model computes the specific acoustic radiation impedance of a very small circular vent in a flanged configuration. The model includes thermoviscous losses. The radiation impedance is fitted using a simple RL circuit which gives a simple lumped representation. The results are used ... Read More
This parametrized model can be used to simulate the hopping hoop problem. A rolling ring with a point mass on the perimeter can, under certain conditions, jump up from the surface on which it is rolling. A more detailed description of this model can be found in the blog post "The ... Read More
This example model simulates the long-path echo of trumpet sounds reflected from a building 500 m away. The echo can only be heard at night because of the acoustic ray refraction in the atmosphere with different temperature profiles. The model is solved using the ray tracing in the ... Read More
