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.
One of the ways we can simplify and reduce the size and computational complexity of a finite element model is by using any symmetries present in a model. In this entry, you can find three practical examples highlighting how to exploit symmetries in RF or wave optics modeling. They all ... 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
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
The liquid electrolyte in lithium-ion batteries (LIBs) typically consists of a lithium salt, such as LiPF6, dissolved in one or several solvents. Commercial LIBs commonly employ a mix of multiple hydrocarbon-based solvents along with additional additives. In an electrolyte consisting of ... 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 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
