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 presentation and series of models show how to use the Deformed Mesh interfaces to model small and large translations and rotations of objects. A more detailed description of these models can be seen in the blog post Model Translational Motion with the Deformed Mesh Interfaces and ... Read More
The heat exchanger in this tutorial model contains a dynamic wall with an oscillating wave shape. The deformation induces mixing in the fluid and reduces the formation of thermal boundary layers. Hence, it increases heat transfer between the walls and the fluid. In addition, the wave ... Read More
This model simulates the separation and mixing of a suspension with light and heavy particles. Initially the distribution of both particle populations is homogeneous throughout the fluid. Before the impeller starts rotating, the fluid and the two particle populations tend to separate ... Read More
This model demonstrates the use of boundary element method in the Electromagnetic Waves, Boundary Element interface to model an optical Yagi-Uda antenna. The antenna is driven by an electrical point dipole, which is implemented through the background field. The field distribution around ... Read More
This example shows the behavior of the coupled damage-plasticity material model for concrete when subjected to different loading conditions. Read More
A fuel cell unit cell is modeled using the full Butler-Volmer expression for the anodic and cathodic charge transfer reactions. The anodic and cathodic overpotentials depend on the local ionic and electronic potentials, which are obtained from the charge balance equations for ionic and ... Read More
In this tutorial, a filter system for a diesel engine is modeled, including a soot layer development and oxidization. The build-up of the layer is held in check by both catalytic and non-catalytic reactions, where carbon is oxidized to carbon monoxide and carbon dioxide, which in turn ... Read More
This is a benchmark model for the 2D axisymmetric formulation of the Electromagnetic Waves, Frequency Domain interface that is available with the RF Module. The problem is to find the resonant frequencies and fields inside an axisymmetric cavity with rectangular cross-section and ... Read More
This model presents a practical and efficient method to compute the sound transmission loss (STL) through a building component. Specifically, this example treats the case of a double-glazed window. The method used here is valid for structural components that have a small influence on ... Read More
This is a simple yet powerful simulation app for designing a two-dimensional reflective metalens. This metalens consists of a array of glass nanopillars on a metal substrate. Initially, the app determines the optimal grating parameters for a specific wavelength and calculates the ... Read More
