The Application Builder and COMSOL Server

Bring Multiphysics to Everyone

Make Mathematical Models Accessible to All Throughout Your Organization

The traditional computational modeling workflow involves creating a geometry, defining all of the necessary materials and physics, meshing and solving the model, and visualizing and postprocessing the results. Making any changes thereafter requires going back to previous steps and redoing them, which demands intimate knowledge of the original model.

Now, engineers can use COMSOL Multiphysics® software to instead wrap their model in a user-friendly interface that allows them or someone else to focus on the changes that matter – without requiring foreknowledge of the underlying model.

Amplify the Simulation Value at Your Organization

Using the Application Builder, which is included in the COMSOL Multiphysics® software, engineers can build applications with intuitive user interfaces that are fully customizable based on design needs and that suit a wide variety of purposes. Basic knowledge of how to use COMSOL Multiphysics is the only prerequisite to creating apps from a COMSOL® software model – no special training or additional software is needed.


The Application Builder was designed to make it easy to build applications. You can add user interface elements (e.g., buttons, inputs, outputs, graphs, and more) with the click of a button and quickly design powerful apps with the drag-and-drop feature. You can also take advantage of the built-in Java® API with tools that write code for you.

Deploy Apps with the COMSOL Server™ Software

To bring mathematical models to everyone within your company, you can use the COMSOL Server™ software as an app-distribution platform. Your colleagues can interface with COMSOL Server in order to run your apps on their own, over your organization's private network. Watch the video below to see how it works and how the Application Builder and the COMSOL Server software fit within the simulation modeling workflow.


You can take your apps with you wherever you go throughout the world if you have a COMSOL Server™ license. With this platform, simulation apps can be accessed on computers as well as smartphones and tablets, and run in a web browser or in a free COMSOL desktop client.

The COMSOL Server™ license will allow you to host COMSOL Server on your own computer or your organization's private network. Your verified users throughout the world can run your apps or their own on your COMSOL Server license, and they can run up to four sessions in parallel. Any person affiliated with an academic institution can run their apps on the Academic Server license for academic use. Furthermore, when you update your apps on COMSOL Server they will be made available immediately so that your users are always running the latest version.
