COMSOL Defines the Standard for Simulation App Design with the Release of COMSOL Multiphysics® Version 5.1

Friday, Apr 24, 2015

COMSOL Multiphysics version 5.1 delivers the first integrated software environment that supports the creation of multiphysics models and simulations as well as the building and sharing of easy-to-use simulation apps.

COMSOL, the leading provider of multiphysics modeling and simulation software, today announced the release of the COMSOL Multiphysics® software version 5.1, the first and only integrated simulation environment for building multiphysics models and for creating and sharing easy-to-use simulation apps. Simulation experts can now benefit from a fully integrated environment where they can create models with COMSOL Multiphysics, build simulation apps with the Application Builder, and share these apps with non-experts via COMSOL Server™. COMSOL software version 5.1 enhances user experience and productivity by allowing users to seamlessly combine model setup with application design from within a single interface. Major upgrades to the Application Builder include full integration between the Model Builder and Application Builder, improved layout tools for app design, and LiveLink™ for Excel® capabilities in applications. Customers will also benefit from the flexibility of being able to run applications on multiple computers with COMSOL Server.

Going from Model to App Is Quick and Easy

In COMSOL Multiphysics 5.1, the Model Builder and Application Builder have been merged into one unified and interactive environment. While building an app, an engineer can easily switch between the Model Builder and Application Builder and make updates to both the model and app simultaneously. The Application Builder is now accessible directly from the ribbon in COMSOL Multiphysics, where the user can simply switch to the app design environment and continue working in just one click. Additionally, both models and apps can be saved in the unified .mph file format.

“The Application Builder is the only application design environment where the user can create multiphysics apps not only within a single software environment, but within a single window using the same file format,” said Bjorn Sjodin, VP of Product Management. “This innovation streamlines the app design process and allows simulation apps to become a truly game-changing engineering solution that will bring powerful design capabilities to non-experts.”


The Corrugated Circular Horn Antenna demo app lets the user modify the geometry of an antenna in order to optimize its radiation characteristics and aperture cross-polarization ratio at the frequency of interest. This app has been created with the Application Builder available in the COMSOL Multiphysics® software.

This streamlined integration of the Model Builder and Application Builder allows model data to be exchanged between the two tools from within the same environment. For example, a function or feature available in the Model Builder can be quickly made available in the Application Builder for the application designer to use. There is no need to interface between different software packages and all tools needed are readily available. Additionally, for instances where the application designer wishes to implement highly-customized commands and operations, code generation is greatly simplified in version 5.1 and many template codes are provided.

“COMSOL today defined the standard for user experience in simulation application design by integrating model building and app design tools into a single environment,” said Svante Littmarck, CEO of COMSOL, Inc. “COMSOL 5.1 delivers additional features that provide our customers with highly productive tools to build and share their simulation applications with users everywhere.
