# Application Gallery

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. To download the MPH-files, log in or create a COMSOL Access account that is associated with a valid COMSOL license. 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.

### Electrical Heating in a Busbar Assembly

Model of electrical heating of a busbar that demonstrates how to use LiveLink™ for SolidWorks® together with LiveLink™ for MATLAB®. The MPH-file required to run the model can be found in [Electrical Heating in a Busbar Assembly](/model/electrical-heating-in-a-busbar-assembly-9219) Read More

### Temperature Distribution in a Vacuum Flask

This example solves for the temperature distribution inside a vacuum flask holding hot coffee. The main purpose is to illustrate how to use MATLAB functions to define material properties and boundary conditions. Read More

### Convective Heat Transfer with Pseudo-Periodicity

This model simulates convective heat transfer in a channel filled with water. To reduce memory requirements, the model is solved repeatedly on a pseudo-periodic section of the channel. Each solution corresponds to a different section, and before each solution step the temperature at the ... Read More

### Domain Activation and Deactivation

Heating of an object from alternating regions is one example where the modeling technique of activating and deactivating physics on domains can be useful. This model demonstrates how you can apply this technique using LiveLink™ for MATLAB®. Read More

### Homogenization in a Chemical Reactor

This model illustrates how to simulate a periodic homogenization process in a space dependent chemical reactor model. This homogenization removes concentration gradients in the reactor at a set time interval. The model demonstrates a technique by which you can first stop the time ... Read More
