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.
This model solves the Boltzmann equation in the two-term approximation for a background of molecular and atomic hydrogen. Electron mobility and source terms are computed by suitable integration of the electron energy distribution function over electron impact cross sections. Read More
Extending the Tuning Fork model, this example shows how to set up an Optimization Study to determine the prong length at which the fork vibrates at the standard concert pitch, 440 Hz. Read More
This model illustrates how to improve the symmetry of a wet chemical etching process by varying the convection and chemical concentration as a function time. Read More
The katana is a legendary Japanese sword used by the samurai in olden days. Here, we present a simple model where we simulate a differential hardening process to explore some of the features of the katana. Learn more in this related blog post: Modeling the Differential Quenching of a ... 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 Radiofrequency Tissue Ablation Using Simulation". Read More
This model demonstrates how to use the built-in shape optimization functionality to improve the performance of a plate heat exchanger. The optimization reduces the path immediately in front of the inlets and outlets to increase the length of typical streamlines. This leads to a improved ... Read More
Light collimation or focusing is a basic task often needed when working with lasers in the lab where singlets are used due to their simplicity. If a plano-convex lens is used for the task, there is a correct lens orientation that minimizes aberrations. A useful rule-of-thumb is to ... Read More
This application illustrates a modeling approach for deriving physically consistent simplified models in the Acoustics Module. The approach consists of converting complex sub-components to an impedance boundary condition and otherwise using simple acoustics throughout the COMSOL model. ... Read More
The purpose of this application is to generate response spectra from a time history which can consist of either measured data on a file, or an analytical function. Primarily, the target is to provide input to a response spectrum analysis. The graphs can, however, also be used to ... Read More
This model demonstrates how to couple the Radiative Beam in Absorbing Media interface to the Radiation in Absorbing-Scattering Media interface. To learn more about this model, see our accompanying blog post “Modeling Absorption and Scattering of Collimated Light”. Read More
