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 model analyses the noise generated by an electric motor during its operation at different speeds of rotation. The type of electric motor analyzed, a permanent magnet synchronous motor (PMSM) uses permanent magnets in the rotor and a variable frequency current traveling through the ... Read More
Échelle spectrographs are commonly used in astronomy for high-resolution analyses of stellar atmospheres and for precision Doppler velocimetry. This tutorial simulates a "white pupil" form of this instrument. It makes use of several parts from the COMSOL Part Library and demonstrates the ... Read More
This app demonstrates the following: Dynamic help system using card stacks Multiple components (1D and 3D) in a single app Toggle buttons in the ribbon for showing different input, hiding/showing geometry selections, and for dynamic help Geometry parts and parameterized geometries ... Read More
Tutorials in this series deal with creating and manipulation of boundary layer meshes. In these tutorials you will learn how to set up a boundary layer mesh and modify the settings for an automatically created boundary layer mesh. For physics-controlled meshing a boundary layer mesh is ... Read More
The model studies optimal material distribution in a hook, which is symmetric about the z plane and consists of a linear elastic material, structural steel. It is subjected to two distributed edge load cases: One at the tip of the hook and one along its lower inner curve. The geometry is ... Read More
This is a full vibro-electroacoustic simulation of a balanced armature transducer (BAT or also known as a receiver in some industries) which is a high-performance miniature loudspeaker often used in hearing aids and other in-ear audio products such as earbuds. The model is set up and ... Read More
Metal hydride tanks offer safe hydrogen storage, thanks to their low reactivity, and a relatively high hydrogen density. When developing metal hydride hydrogen tank designs, modeling and simulation is useful for optimizing operating conditions, such as gas composition, pressure, and ... Read More
A Mach-Zehnder modulator is used for controlling the amplitude of an optical wave. The input waveguide is split up into two waveguide interferometer arms. If a voltage is applied across one of the arms, a phase shift is induced for the wave passing through that arm. When the two arms are ... Read More
This example illustrates how to model the transport of different contaminants through a ceramic water filter candle with an activated carbon core. These types of water filters can be found in table top gravity filters, as well as attached to the faucet or as part of a larger reverse ... Read More
This tutorial models the intercoupled electrochemical reactions, charge and species transport as well as heat transfer in a polymer electrolyte membrane (PEM) fuel cell. For the gas flow fields, straight channels are used on the hydrogen anode side, whereas a mesh structure is used on ... Read More
