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 considers the thermal cracking of acetone, which is a key step in the production of acetic anhydride. The gas phase reaction takes place under nonisothermal conditions in a plug-flow reactor. As the cracking chemistry is endothermic, control over the temperature in the ... Read More
A thin-walled container made of rolled steel is subjected to an internal overpressure. As an effect of the manufacturing method, the out-of- plane direction has a higher yield stress than the other two directions. Hill’s orthotropic plasticity is used to model the difference in yield ... Read More
This model studies the natural frequencies of a pre-tensioned string using the 2D Wire interface. This is an example of “stress stiffening”; in fact the transverse stiffness of wire elements is directly proportional to the tensile force. Strings made of piano wire have an extremely high ...

A time-varying current induces a time-varying magnetic field. The magnetic field induces currents in neighboring conductors. The induced currents are called eddy currents. In this model, the phenomenon is illustrated by a time-harmonic field simulation as well as a transient analysis, ... Read More
HowTo: Using the EC External I-Terminal The External Couplings in the CIR interface has two flavors that can be used. External I vs. U and External I-terminal. The former has two nodes (it represents a differential external voltage measurement) and when coupling to an EC Terminal ... Read More
The four-point bending test is a conventional test method used to test the mechanical properties of materials subjected to bending. It is a reliability test used for semiconductor packaging and assembly. This model demonstrates the stress analysis of an IGBT module subjected to a four ... Read More
Nanoparticles have become widely used in a range of applications. For example, in pharmaceuticals, particles on the nanoscale, such as nanocrystals, are often used as an effective means of drug delivery. Meanwhile in material sciences, nanoparticle coating is an increasingly common way ... Read More
This application uses the Chemical Reaction Engineering Module to study an elementary, exothermic, irreversible reaction in a tubular reactor (liquid phase, laminar flow regime). To keep its temperature down, the reactor uses a cooling jacket with a constant coolant temperature. The ... Read More
This tutorial minimizes the mass of a bracket that is synchronized from PTC Creo Parametric™ via the LiveLink™ interface. There are limits both for the lowest natural frequency, and for the maximum stress in a static load case. The size and position for a number of ... Read More
This model demonstrates how to vary the inlet temperature in a superheated steam drying process so as to minimize the time, while constraining both the energy consumption and the final moisture content. Read More
