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.
The use of Aluminum (Al) isolator is a commonly employed mitigation strategy for galvanic corrosion between magnesium alloy (Mg) and mild steel (MS). The present model demonstrates the effect of Al isolator thickness on galvanic corrosion severity using a parametric study. The electrode ... Read More
The noise emitted from an electrical machine can have many sources. In this example, acoustic noise from vibrations created by magnetic force variation is studied. Such noise is often audible at twice the excitation frequency but can also occur at higher frequencies or harmonics of the ... Read More
The following model examines unsteady, incompressible flow past a long cylinder placed in a channel at right angle to the oncoming fluid. The cylinder is offset somewhat from the center of the flow to make the steady-state symmetrical flow unstable. The simulation time necessary for a ... Read More
The underlying physics of a capacitively coupled plasma is rather complicated, even for rather simple geometric configurations and plasma chemistries. This model benchmarks the Capacitively Coupled Plasma physics interface against many different codes. Read More
Micromixers can either be static or dynamic depending on the required mixing time and length scale. For static mixers, the Reynolds number has to be suitable high to induce turbulence enhanced mixing. Often micromixers operate in the laminar flow regime due to their small characteristic ...

This app demonstrates the following: How an app can be used as a teaching tool An 8 question multiple choice quiz where the answers can be sent to the grader by email This app calculates the equilibrium compositions in gas phase conversion of ethylene to ethanol. It allows you to ... Read More
This tutorial demonstrates a structural analysis of a simple telescope. The deformation of the telescope structure under gravity is examined and the effect on image quality is demonstrated. Read More
In this example, the Bergstrom–Boyce material model is used to capture the nonequilibrium behavior of carbon-black-filled chloroprene rubber under a strain history that alternates compression with relaxation. Results are verified against experimental and numerical results taken from ... Read More
The Free Molecular Flow interface, available in the Molecular Flow Module, is an efficient tool for modeling extremely rarefied gases when the gas molecules move much faster than any geometric entities in the domain. For turbomolecular pumps, in which the blades move at speeds comparable ... Read More
During an internal short circuit of a battery, the two electrode materials are internally and electronically interconnected, giving rise to high local current densities. Internal short circuits may occur in a lithium-ion battery due to, for instance, lithium dendrite formation or a ... Read More
