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 shows how to use the features of the Heat Transfer Module to reduce the computation time and memory usage in view factor computations. Illustrative results of speedup and memory usage reduction are given on a benchmark model. The solution is not computed, only the view ... Read More
A deceptively simple system of two species and two reactions, describing the autocatalytic conversion of a substance, is shown to display a surprisingly exotic behavior. Starting from a 0D CSTR description, a 2D reaction-diffusion problem is formulated showing rich patterns stemming from ... Read More
In this model, we introduce a cloaking method using an electrically tuned monolayer of graphene. We will show that when a cylindrical dielectric scatterer is covered in graphene, the scattering cross section is greatly reduced at the designated frequency, making it electromagnetically ... Read More
In this tutorial you will learn how to use selections when creating the parametric geometry for the analysis of a steam reformer, and set up the selections needed for the physics definitions. The multiphysics analysis of the steam reformer is described in the model Steam Reformer found ... Read More
A diplexer is a device that combines or splits signals into two different frequency bands, widely used in mobile communication systems. This model simulates splitting properties using a simplified 2D geometry. The computed S-parameters and electric fields at the lower and upper bands ... Read More
Isotropic compression is a common material test in soil mechanics. The modified Cam-Clay (MCC) model describes the relation between the void ratio and the logarithm of the pressure. In this example, a cylindrical soil sample under isotropic compression is simulated. It is verified that, ... Read More
This tutorial shows how to model the tubular permanent magnet generator in 2D axisymmetry. The generator consists of a modular stationary stator and moving/oscillating slider. The stator is made of three-phase multiturn windings and an iron core. The slider is made of permanent magnets ... Read More
Interference fit is a technique used to join or fit one part over or around another part. The internal part is cooled, so that it shrinks, and is then fitted. Once the part heats up again and expands, a contact pressure builds up at the interface between the two parts. This type of ... Read More
This model demonstrates how the Free Shape Boundary feature can be used to perform shape optimization on a design found with topology optimization. The model uses the same objective and constraint as the original, which results in a slightly higher stiffness for the same mass. Read More
Fatigue testing of nonlinear materials with creep mechanism is a time-consuming process. In accelerated life testing the experiment time is greatly reduced by subjecting the material to testing conditions in excess of the operating one. In the model an aggressive thermal load cycle is ... Read More
