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.
In this example, an CF4/O2 plasma reactor at low pressure is studied using a global model. Parametric sweeps for pressure and oxygen mole fraction are computed. Read More
This model demonstrates 2D topology optimization for the problem of minimum mass subject to a compliance constraint and a stress constraint. The stress constraint is implemented with a P-norm global aggregation function. The stress input to this is interpolated differently than the Young ... Read More
This example shows how to model tissue ablation through applying RF radiation. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Study Radio Frequency Tissue Ablation Using Simulation". Read More
This model aims to demonstrate how a multilayer insulation can affect the temperature distribution of a satellite orbiting around the Earth. It is based on the Spacecraft Thermal Analysis model available in the Application Library. Read More
The purpose of this model is to visualize the electric potential in an electrochemical cell, for example a battery. This is done at OCV and during operation. In a battery, this would correspond to OCV, discharge, and recharge. The potential profile is explained both for cells with planar ... Read More
Stimulated Brillouin Scattering (SBS) describes a nonlinear interaction between light and sound. In optical fibers, SBS can be detrimental for power or communication purposes, but can be leveraged for sensing applications. The SBS gain spectrum quantifies the optic-acoustic mode ... Read More
In this model, an axial field magnetic gear with a gear ratio of 5:2 is modeled. Both the high-speed and low-speed rotors consist of permanent magnets and back iron. The low-speed rotor consists of five pole pairs, while the high-speed rotor consists of two pole pairs and the stationary ... Read More
This model demonstrates dielectric barrier discharge (DBD) in air subjected to an AC applied voltage. As the voltage amplitude increases, the discharge intensity correspondingly strengthens. Furthermore, the dominant component of the discharge current transitions from displacement ... Read More
Creating irregular geometries can be a good solution, even the only option, for some types of applications. These files present a way to use a text file with material properties defined in coordinates to assign different materials even though there is only one regular domain. The same ... Read More
A classic way of estimating pi is by using the Monte Carlo method. This involves randomly placing points inside a square and counting how many lie within a circle inscribed in the square. The ratio of points inside the circle to the number of points in total can be used to approximate ... Read More
