Where Can I Find COMSOL Multiphysics Tutorial Models?

There are two main resources for finding COMSOL Multiphysics tutorial models: our online Model Gallery and the Model Library within the software. We also continuously push out model updates that you can download to your Model Library. Here’s your guide to what these resources are and how to use them.

Model Library

If you have installed COMSOL Multiphysics, you will have access to the Model Library. This is exactly what it sounds like: a library chock-full of example models to help you get started. Each tutorial available in the Model Library comes with a model MPH-file and a PDF with the step-by-step instructions so you can learn how to build it on your own. There are many application-specific tutorial models, so the more modules you have installed, the more tutorial models you will have at your disposal.

Note: If you are on trial, you will be able to access all of the Model Library examples for the duration of your trial.

Where to Find the COMSOL Multiphysics Model Library

Within the COMSOL Multiphysics® software, click on the “File” (or “Windows” if you are using Mac® or Linux®) menu item, then select the “Model Libraries” option from the drop-down. This will pull up a list of all the add-on modules you have installed.

If you have a specific model in mind, you can search for its full or partial name. Similarly, you can find models that use a particular physics interface or feature, or models that address a specific field of technology using suitable keywords.

Otherwise, you can browse the libraries. The models are grouped by module, so to hone in on your area of interest, you just click on one of the arrows to expand. All products will have an additional grouping by category, such as in the example below. To preview a tutorial model before opening it, simply click on it:

As you can see above, you can choose to open either the model MPH-file, a PDF document, or both the model file and PDF. The document contains complete step-by-step instructions on how to set up and run the model.

Here’s an example of what the PDF looks like:

When you click on “Open Model” or “Open Model and PDF”, you will be able to view and work with the MPH-file:

Alternatively, to open the model, you can right-click the model name in the Model Libraries window, and then select the appropriate item from the context menu. To save space, some of the models come with compact MPH-files with all settings for the model but without built meshes and solution data. If a full MPH-file is available for download, the model’s context menu includes a “Download Full Model” item. From the context menu, you can also open the “Help” window to display HTML model documentation in the COMSOL Desktop while you work with the model.

How to Add Your Own Model Library

If you would like to create your own Model Library, you can do so as well. First, save your model(s) to a folder somewhere on your computer. Next, go to “File” and select “Preferences” from the drop-down menu. If you click on “Model Libraries”, you will get the following screen:

Right above the “Factory Settings” button, you can see a set of icons. The one to the far left is the “Add User Model Library” icon. After clicking on that, you will get to a new window where you should choose the “Browse for Folder” option. Select the folder that contains your model(s). This will now show up in the Model Libraries list. Finally, click “OK”.

Now, your custom Model Library will show up as an option within the standard list of Model Libraries (seen in the first screenshot of this blog post).

Model Updates

We regularly push out updates to the Model Library, including both brand new models and updates to existing ones. All of the updated models include full step-by-step instructions. Because we send out updates very frequently, we do not send you notifications each time. Instead, you will need to check for yourself.

How to Activate COMSOL Multiphysics Model Updates

To see if there are any new updates available, you need to open the software from your desktop by right-clicking and selecting “Run as Administrator”. Next, click on “File”, then select “Help” ( or click “Help” if you are using Mac or Linux). From there, choose the “Update COMSOL Model Library” option.

You have the option to download the full models with solutions or compact versions without solutions (this is faster). Once you have made your decision, you go to “Find Models” and choose which ones you would like to update. Note that all of them are checked by default, so if you do not want to activate all of them at once, you can uncheck some. When you are satisfied with your selection, click on the “Download” button.

Model Gallery

You may recognize our online Model Gallery if you’ve clicked on links from other blog posts that feature COMSOL Multiphysics models.

This resource contains everything you will find in the Model Library as well as other tutorials that may not have complete instructions to go along with them. Models without full instructions are usually accompanied by PowerPoint® slides. All of the documentation is available for instant download, and if you sign into your COMSOL Access account, you can also download the MPH-files from the Model Gallery.

Happy modeling!
