Using the Help Tools in COMSOL Multiphysics® for Modeling Guidance

Amelia Halliday | January 10, 2017

The COMSOL Multiphysics® software helps you find solutions to your engineering questions, but you may also have questions on using the simulation software itself. Therefore, we’ve created resources to guide your modeling process. In this blog post, we discuss three help tools that you can access in COMSOL Multiphysics: the Help window, Documentation window, and Application Library. We also link to a video that shows you how to access and use these tools at the end of this post.

When designing needles for drug delivery, one major challenge is balancing the comfort of the patient with the effectiveness of the injection. By applying an approach that combines “first principles” thinking and modeling, Eli Lilly and Company optimized the design of a needle for an insulin injection pen, while keeping patient experience in mind. In a keynote talk from the COMSOL Conference 2016 Boston, Bernard McGarvey of Eli Lilly discusses this process.

To optimize your modeling processes, there are a number of built-in materials available for you to use in the COMSOL Multiphysics® software. Along with these materials are features and functionality that allow you to efficiently assign materials to geometric entities in your model. These tools help expedite the process of assigning materials, specifying material properties, and even comparing the impact of different materials on your simulation results. Here, we’ll highlight three tutorial videos that showcase how to use such tools.

When you are creating a model, it can sometimes be difficult to keep track of all the parts in the geometry, including the conditions or constraints that apply to each section. This is especially true when dealing with large, complex geometries and multiple physics interfaces. In COMSOL Multiphysics, tools like named selections help maintain your model setup and streamline your workflow. Here’s a look at three tutorial videos demonstrating how to create and utilize Explicit, coordinate-based, Boolean, and adjacent selections.

Simulation is a powerful tool that enables you to obtain a holistic view of your design’s performance. While the physics you are studying may be complex, the environment in which you run such studies doesn’t have to be. This rationale has served as the logic behind continuously optimizing the user interface (UI) in the COMSOL Multiphysics® software for ease-of-use. Several tutorial videos, three of which are highlighted here, guide you on how to navigate the environment and utilize its tools.

As you are learning to create apps in the Application Builder, we want you to take advantage of all of the tools that are available to you. The video featured here introduces you to the Editor Tools, Model Data Access, and Record Code features and demonstrates how to use them. To do so, we add a button to our app that can switch the type of plot shown in the graphics window.

If you are in the process of learning how to build simulation apps, the video shown here is a fantastic introduction to writing methods. With a fully functioning app already built, we create a method with the click of a button and then proceed to play a sound, include user inputs, and add an if-else statement. All of this is done using Language Elements, which are included in the Method Editor to help make creating methods a breeze.

An important element in the design of any simulation app is organization. Maintaining an orderly structure makes it easier for you to build the app and also enhances the usability experience for app users. Today, we will show you how to create organized apps in COMSOL Multiphysics with the help of subforms and form collections.

When a user running your COMSOL app finds a particularly interesting set of results, they might need to save their app so they can come back to it later. Without save options, you’d have to re-run the simulation later with the input parameters they gave you. That would be very inefficient and defeat the purpose of creating simulation apps. Today, we’ll show you how to add a file menu with save options in your app.
