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.
A line array of eleven spherical hydrophones embedded in a neoprene coating is modeled in 3D. The sensitivity of the array is analyzed with regard to varying angles of incidence of the background pressure field. The array directivity function is computed and compared to the analytical ... Read More
This model illustrates how to simulate a periodic homogenization process in a space dependent chemical reactor model. This homogenization removes concentration gradients in the reactor at a set time interval. The model demonstrates a technique by which you can first stop the time ... 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
In COMSOL Multiphysics®, you can easily define moving loads and constraints. These three models demonstrate three different approaches for modeling moving loads in the COMSOL® software, including: A user-defined expression A text file of positions over time An imported ... Read More
This app simulates a micromixer based on an imported CAD geometry. The app shows how you can use the Application Builder to build an app that can handle CAD import and let the user interactively select boundary conditions. The app shows how this can be done without any programming using ... Read More
This example exemplifies how to model the Beer-Lambert law using the core functionality of COMSOL Multiphysics. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Modeling Laser-Material Interactions with the Beer-Lambert Law". Read More
One of the possible formats when working with scanned data is images for the slices of an MRI or CT scan. This is an example with images from the cross sections of the different levels of a human head. In short, the procedure includes creating curve objects of each of the images using ... Read More
The Dzhanibekov effect, also called the intermediate axis theorem or tennis racket theorem, describes the behavior of a rigid body with three distinct principal moments of inertia. This simulation app can be used to test the Dzhanibekov effect in three different geometries, including a ... Read More
This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in Solid Edge® by using the LiveLink™ interface with a parametric sweep. Read More
This model illustrates the working principle of an axial homopolar induction bearing. An electrically conducting rotor rotating in a magnetic field produced by a permanent magnets induces eddy currents on the conducting rotor. The eddy currents, in turn, produce a magnetic field that ... Read More
