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 you are working with foreign CAD or ECAD data, such as files in the STEP, GDS, or IGES file formats, or any of the other supported formats, you may think that you need to re-import a new CAD file and start your modeling over from scratch if you want to study a change in size or ... Read More
Bicycle wheels are laced tangentially if they are intended to be used with disc brakes, because a radial pattern gives rise to larger forces in the rim. Otherwise, these rim forces are largely independent of the braking force. Read More
This example exemplifies how to compute the design sensitivities of your COMSOL Multiphysics® model. A more detailed description of the modeling process can be seen in the blog post "Computing Design Sensitivities in COMSOL Multiphysics". Read More
This example demonstrates an app that utilizes the LiveLink™ interface for Solid Edge® to run simulations on CAD designs. Read More
This example exemplifies how to model the impedance of a waveguide of varying cross sectional area. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Computing the Impedance of a Corrugated Waveguide". Read More
This model demonstrates how to solve an ordinary differential equation for the motion of a spacecraft about a planet. In addition to computing the path, it is possible to use several results presentation features to make interesting visualizations. For a full description of this model, ... Read More
This model shows how to simulate moisture redistribution inside a wall with capillary active interior insulation. The wall consists of three layers: brick, mortar and insulating material. At the beginning of simulation, there is a sudden change in vapor pressure and temperature at ... Read More
Electrochromic devices (ECDs) may be employed in ”smart” windows, for instance in buildings or motor cycle visors, where the transparency of the device can be controlled by applying a voltage. ECDs make use of the fact that the absorbance of visual light for a chemical species in a ... Read More
This model demonstrate how to simulate ray tracing in a pinhole camera viewing a solar eclipse. To keep the model dimensions in check, the Sun and Moon are approximated using planar discs with the appropriate angular size (~0.5 degree) relative to the pinhole. In this example, the ... Read More
Solving very large pressure acoustics models in the frequency domain can be challenging. Several iterative solver suggestions exist for the default physics setups and the default quadratic Lagrange discretization. For very large models it can be advantageous to switch from quadratic to ... Read More
