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. To download the MPH-files, log in or create a COMSOL Access account that is associated with a valid COMSOL license. 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.
Shape Optimization of a Tesla Microvalve
The topology optimized Tesla microvalve is used as inspiration for a initial geometry. Second order Bernstein polynomials are used to perturb the shape of the geometry. The resulting design is remeshed in the deformed configuration and the performance is investigated for a range of ... Read More
Using Text Files to Automate Model Preprocessing
This example demonstrates how to set up text files to use when preprocessing models that contain hundreds of parts. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "[Automate Model Preprocessing with the Application Builder](https://www.comsol.com/blogs/automate-model-preprocessing-with-the-application-builder/) ...

Rotating Plate in a Unidirectional Molecular Flow
This model computes the particle flux, number density and pressure on the surface of a plate that rotates in a highly directional molecular flow. The results obtained are compared with those from other, approximate, techniques for computing molecular flows. Read More
Geometric Parameter Optimization of a Tuning Fork
This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Inventor via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz. Read More
