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.
Ion implantation is used extensively in the semiconductor industry to implant dopants into wafers. Within an ion implanter, ions generated within an ion source are accelerated by an electric field to achieve the desired implant energy. Ions of the correct charge state are selected by ... Read More
One method for removing cancerous tumors from healthy tissue is to heat the malignant tissue to a critical temperature that kills the cancer cells. This example accomplishes the localized heating by inserting a four-armed electric probe through which an electric current runs. Equations ... Read More
This model computes the ion energy distribution function (IEDF) for a commercial capacitively coupled plasma reactor. The results show good agreement with experimental data. Read More
This tutorial model explains how to extract lumped matrices by means of the Stationary Source Sweep study. The capacitance matrix of a five-terminal system is used to infer the position of a metallic object similar to real-world capacitive position sensors. The example illustrates the ... Read More
In this model you study the force-deflection relation of a car door seal made from a soft rubber material. The model uses a hyperelastic material model together with formulations that can account for the large deformations and contact conditions. Read More
Bearings are used in machines to reduce the friction between moving parts and thereby smooth their relative motion. Rolling element bearings are one of the most widely used bearings, where rolling elements or rollers are used to support the load. These rollers can be of different shapes; ... Read More
Electromagnetic analysis of a 400kVA, 15kV/400V three-phase power transformer with Y-d connection and multiple primary and secondary coils with hundreds of turns. The model features the standard open- and short-circuit test in 2Daxi and 3D simulations to estimate electrical quantities ... Read More
This model shows how to use the scattered-field formulation to compute the transmission coefficient for impinging P and S plane elastic waves onto a finite-size phononic crystal. The transmission tends to zero in the frequency ranges corresponding to P- and S-wave band gaps, as ... Read More
