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 full vibro-electroacoustic simulation of a balanced armature transducer (BAT 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. The model is set up using a linear frequency ... Read More
The following example demonstrates techniques for modeling a fluid-structure interaction containing two fluid phases in COMSOL Multiphysics. It illustrates how a heavier fluid can induce movement in an obstacle using the arbitrary Lagrangian-Eulerian (ALE) technique along with the Two ... Read More
Magnetostrictive transduction is used in sonars, acoustic devices, active vibration, and position control and fuel injection systems. The transducer has a steel housing enclosing a drive coil. A magnetostrictive material is placed in the core, which works as an actuator when a magnetic ... Read More
Follow this tutorial series to learn about how to work with imported surface meshes. The instructions detail how to import STL files of three vertebrae and two intervertebral discs as well as how to repair holes, misaligned mesh vertices, and intersecting elements. It further ... Read More
Pitting corrosion is a type of localized corrosion by which local cavities, pits, are formed on an initially smooth metal surface. A pit may be initialized by surface defects, such as an inhomogeneities in composition or shape, or mechanical abuse resulting in a small scratch or dent. ... Read More
This example shows how to compute thermally induced stresses in a turbine stator blade using the Thermal Stress, Solid interface. The conditions within gas turbines are extreme. The pressure can be as high as 40 bar, and the temperature more than 1000 K. Any new component must therefore ... Read More
This model demonstrates the ability to simulate Multibody Dynamics in COMSOL. It comprises a multilink mechanism that is used in an antique automobile as a gearshift lever. It was created out of curiosity to find out how large forces are on the individual components. The model uses ... Read More
The electrostatically tunable parallel plate capacitor in this example is a typical component in various MEMS devices for radio frequencies that range between 300 MHz and 300 GHz. You can modify the distance between the two plates, as the applied voltage changes, through a spring ... Read More
In microfluidic devices it is a challenge to mix different fluids. A method is to use acoustic streaming to create a flow which enhances the mixing of two fluids. In this model the vibrations of PDMS structures in a channel induces fast acoustic streaming used for mixing a diluted ... Read More
The first stop for polluted water entering a water work is normally a large tank, where large particles are left to settle. Generally, gravity settling is an economical method of separating particles. If the fluid in the tank is moving at a controlled low velocity, the particles can be ... Read More
