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.

Modeling Irregular Shapes by Using Interpolation and Image Data

This file shows how to create a surface of an irregular shape based on text, image, or elevation data. This approach is best suited for data where the height (or elevation) is a function of _x_- and _y_-coordinates. The data is of the Matterhorn, a European mountain located in the ... Read More

Simulating Action Potential with the Hodgkin-Huxley Model

This app allows you to simulate the action potential in a cell's membrane using the Hodgkin-Huxley model. As it is presented in the form of a simulation app, you can change the input parameters for potential, conductance, and membrane capacitance to study their effects on the dynamics ... Read More

Helical Static Mixer

Helical static mixers are often used to mix monomers and initiators that then react during a polymerization process. The purpose of the Helical Static Mixer application is to demonstrate this mixing process as well as the use of parts and parameterized geometries when building apps. The ... Read More

Modifying Imported CAD Geometry with the Deformed Geometry Interface

When you are working with foreign CAD or ECAD data, such as files in the STEP, GDS, or IGES file formats, or any of the other supported formats, you may think that you need to re-import a new CAD file and start your modeling over from scratch if you want to study a change in size or ... Read More

Carburizing of gears

The model illustrates how to simulate carburizing, a heat treatment process producing a wear resistant surface. The model solves heat transfer in solids, carbon diffusion and phase transformation of austenite into martensite and pearlite. Read More

Job Sequences to Save Data After Solving a Model

These examples demonstrate how to use a job sequence to perform a programmatic sequence of operations, including solving; saving the model to file; and generating and exporting plot groups, results, and images. In the blog post associated with these files, "[How to Use Job Sequences to ... Read More

How to Export Images Automatically After Solving

This example demonstrates how to use a parameterized slice plot and animation functionality to export a sequence of images. In addition, the example shows how to use a job sequence to perform a programmatic sequence of operations where the model is first solved and then the image ... Read More

Shock Tube

The compressible Euler equations are implemented in the Wave Form PDE interface with nodal discontinuous Lagrange shape functions to compute the flow in a shock tube. The purpose of this application is to simulate the flow in the tube and estimate the distributions of pressure, density, ... Read More

Using Text Files to Automate Model Preprocessing

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](https://www.comsol.com/blogs/automate-model-preprocessing-with-the-application-builder/) ...
