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 example shows how to set up a piezoelectric transducer problem following the work of Y. Kagawa and T. Yamabuchi. The composite piezoelectric ultrasonic transducer has a cylindrical geometry that consists of a piezoceramic layer, two aluminum layers, and two adhesive layers. The ... Read More
FSI analysis of a sports car side door and side rear view mirror. The model is based on large eddy simulation analysis of a sports car. The flow field is used for a structural analysis of the side mirror and side door to estimate the flow-induced vibrations. Read More
Opto-acoustophoresis is a term used to describe the interplay between acoustics and optical fields. In most cases (including this) the optical field is heating up the material and therefore affecting the acoustic field. In this example of an acoustic trap a set of particle are trapped ... Read More
The powder compaction process is becoming common in the manufacturing industry, thanks to its potential to produce components of complex shape and high strength. In this example, the compaction of iron powder to form an axisymmetric rotational flanged component is analyzed with capped ... Read More
Failure of reinforced concrete structures involves advanced material behavior and interaction between materials. This example demonstrates how to model various stages of the failure of a reinforced concrete beam. The material model includes a coupled damage-plasticity model for the ... Read More
In this example, it is demonstrated how to extend the built-in linear elastic material model to a Cosserat material through the addition of microrotation degrees of freedom. A cylindrical bar under pure torsion is analyzed and the effect of the Cosserat length scale parameter on the ... Read More
The model performs a static analysis on a piezoelectric actuator based on the movement of a cantilever beam, using the Piezoelectric Devices predefined multiphysics interface. Inspired by work done by V. Piefort and A. Benjeddou, it models a sandwich beam using the shear mode of the ... Read More
In this example, the importance of including elastic deformations when analyzing heavily loaded fluid-film bearings is investigated. The structural parts are modeled using the Solid Mechanics interface, while the pressure in the lubricant is determined by the means of the Hydrodynamic ... Read More
This model simulates the dynamics of the shock absorber used in a landing gear mechanism of an aircraft. It analyses the stresses, as well as the heat generated in the landing gear components due to the energy dissipated in the shock absorber. A prismatic joint, with spring and damper, ... Read More
Loudspeaker design is a challenging task, where the design objective is to achieve better sound quality without violating manufacturing and operational constraints. The quality of sound depends on many parameters; one of them is the ability to control, damp, and shift the diaphragm ... Read More
