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 is used on "Heat Transfer with Radiation in Participating Media and the Discrete Ordinates Method" to compare quadrature sets used in the method of discrete ordinates. To assess the performance of quadrature sets in complex geometries, results of incident irradiation and ... Read More
A demultiplexer is a device that directs different frequency bands to different outputs. In this tutorial model, we will design a demultiplexer by performing shape optimization on all initial circular boundaries in a sonic crystal (phononic crystal) configuration. The model uses shape ... Read More
Mechanical precession prevents bicycle pedals from falling off. The model captures this effect using a multibody dynamics simulation together with a contact analysis. A friction coefficient is associated with the contact in order for the model to capture the effect. Read More
This example demonstrates how to set up text files to use when preprocessing models that contain hundreds of parts. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Automate Model Preprocessing with the Application Builder". Read More
This example of a simulation application shows how to add a user-defined license agreement, which you can use to protect applications that you publish and distribute. Read More
This example shows how to create a time-limited and hardware-locked application. It is associated with the section "Time-Limited and Hardware-Locked Applications" in the Application Programming Guide Read More
This tutorial demonstrates how to model the band-to-band tunneling across a p–n junction. The tunneling effect is imitated by defining the User-Defined Recombination domain feature which makes the electrons disappear from the conduction band on the n-side and holes disappear from the ... Read More
Basin-type insulators are critical components in Gas-Insulated Metal-Enclosed Switchgear (GIS). During the manufacturing process, the curing of epoxy resin can generate residual stresses that may lead to the formation of cracks in insulators. Over time, these cracks can cause partial ... Read More
This example exemplifies how to model a Koch snowflake using the Application Builder. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Using the Application Builder to Create a Koch Snowflake". Read More
The model remove details example v63.mph illustrates how to manually add the Remove Details operation and virtual operations to find and remove small details from a model geometry. In the model geometry cleanup example v63.mph, the automatic Geometry Cleanup added Remove Details ... Read More
