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.
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](https://www.comsol.com/blogs/using-the-application-builder-to-create-a-koch-snowflake/)".
This example exemplifies 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](https://www.comsol.com/blogs/automate-model-preprocessing-with-the-application-builder/)".
This example shows how to model the behavior of a thermostat where a delay in its reaction has been implemented. A more detailed description of the phenomenon, and the modeling process, can be seen in the blog post "[How to Implement a Delay in Your Thermostat Simulation](https://www.comsol.com/blogs/how-to-implement-a-delay-in-your-thermostat-simulation/)".
