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.
When high-fidelity measurement microphones are calibrated, a pressure reciprocity calibration method is used. During calibration, two microphones are connected at each end of a closed cylindrical cavity. For the calibration procedure, it is important to understand the acoustic field ... Read More
Fiber composites are widely used in industrial applications. Compared to more traditional metallic engineering materials, fiber composites often have superior specific stiffness and strength properties, and they are often more corrosion resistant. Also, properties like strength, ... Read More
This model exemplifies the analysis of strong wind flow around a solar panel and the corresponding structural displacement due to the wind's load. The solar panel is located in an array of equally spaced identical panels, which allows for the assumption that the periodic flow conditions ... Read More
In this example, the natural frequencies of a double hat beam are studied. The beam is made of two thin steel plates, joined together by spot welds along the flanges. The Spot Welds feature sets up multiple mesh-independent connections between the shells. Read More
This model illustrates the greenhouse effect in a box covered by a plate and exposed to sun radiation over a day. The temperature variation is monitored in two cases: with a plate made of glass, transparent in the solar spectral band and opaque for the ambient solar band with a fully ... Read More
Droplet evaporation is ubiquitous in everyday life, and is essential in many industrial processes such as ink-jet printing, cleaning or coating of surfaces, and phase change heat transfer. In this model, a water droplet placed on a solid substrate evaporates in air. We solve the ... Read More
This is a busbar configuration with an AC analysis. The configuration is similar to the introductory tutorial in the book Introduction to COMSOL Multiphysics. However, two conductors are added to represent a more realistic case of magnetic fields surrounding the busbar. The results ... Read More
This example shows how to set up an ionic polymer-metal composite (IPMC) as an actuator for a robotic manta ray. Two IPCM beams are integrated into the fin and can be controlled independently. The chemomechanical effect is achieved with the Shrinkage and Swelling multiphysics ... Read More
It is more difficult to generate laser emissions in the short-wavelength part of the visible and near visible part of the electromagnetic spectrum than in the long-wavelength part. Nonlinear frequency mixing makes it easier to generate new short wavelengths from existing laser ... Read More
In its simplest form, an optical ring resonator consists of a straight waveguide and a ring waveguide. The waveguides are placed close to each other, making the light affect each between the two structures. If the propagation length around the ring is an integral number of wavelengths, ... Read More
