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 example demonstrates the usage of current terminal to compute the resistive heating of a busbar. Read More
This tutorial shows how to set up a multi-element objective lens. The chosen lens is a Petzval lens with field flattener described in 'Fundamental Optical Design', by M. Kidger, 2001, pg 192. The tutorial demonstrates how to include a geometric sequence using the 'Spherical General Lens ... Read More
This tutorial shows how you can use the Electromechanics interface in COMSOL's MEMS Module to model Electrostriction. Electrostrictive materials (e.g. PMN-PT) exhibit nonlinear strain as a function of electric field. This 2D axisymmetry model uses a parametric sweep of voltage to ... Read More
A quadrupole mass filter (QMF) is a key component of a modern mass spectrometer. A QMF uses direct current (DC) and alternating current (AC) electric fields to analyze positive or negative ions by mass to charge ratio. A QMF consists of 4 parallel rods spaced equidistantly, the ratio of ... Read More
This model demonstrates the switching capability of a liquid crystal (LC) display cell in In-Plane Switching (IPS) configuration. The Oseen-Frank model is used to solve for the LC director (optical axis) distribution when a static electric field is applied. A Weak Form PDE interface is ... Read More
This tutorial model shows how a user-defined coordinate system can be used to create any type of directional polarization of a piezoelectric material. Results are shown for the case of radial polarization of a piezoelectric disk. The piezoelectric material is PZT-5H. The example shows a ... Read More
Microlithography lenses are used to project the image of an integrated circuit onto a silicon substrate. This tutorial demonstrates how to create a 21-element fused silica lens which has a NA of 0.56 which is designed to be used at a wavelength of 248nm. The lens, which has a total ... Read More
Piezoelectric valves are frequently employed in medical and laboratory applications due to their fast response times and quiet operation. Their energy efficient operation, also dissipates little heat, which is often important for these applications. This model shows how to model a ... Read More
This a continuation of the permanent magnet motor model available here . In this model, an heat transfer analysis has been performed to compute the temperature rise for various stator current and rotor speed. A detailed analysis on torque, and losses in iron and copper have then been ... Read More
This model addresses the concept of wireless power transfer by studying the energy coupling between two circular loop antennas tuned for UHF RFID frequency whose size is reduced using chip inductors. The circular loop antenna provides inherent inductive coupling by its shape, and it can ... Read More
