COMSOL releases latest version of software for creating simulation apps

October 8, 2015

COMSOL Inc. brings to the simulation community the only fully integrated environment for creating simulation apps by announcing the pre-release of COMSOL Multiphysics 5.2 at the COMSOL Conference 2015 Boston. As the leading provider of multiphysics modeling and simulation software, COMSOL delivers major productivity updates to COMSOL Multiphysics and COMSOL Server with new features, improved stability and robustness, and faster execution. Version 5.2 offers a more intuitive and improved user experience for building multiphysics models and converting them into simulation apps. Major upgrades to the Application Builder include the new Editor Tools for easy creation of user interface components, commands for dynamic updates of graphics, and more control over the deployment of simulation apps. In version 5.2 running simulation apps using the COMSOL Server™ software in a corporate network or in the cloud is now up to five times faster. Many updates, new features and demo apps are also available for the add-on products in electrical, mechanical, fluid, and chemical areas.

Clearly Communicate Designs with the Application Builder

In COMSOL Multiphysics 5.2, the Application Builder features an optimized workflow with the debut of several features and the new Editor Tools, which makes the creation of user interface components easy and quick. Simulation specialists can now use Editor Tools to bring any model parameter, physics setting, or plot into the user interface of an app with a few mouse clicks. This is one of several tools available that simulation experts can harness to create truly practical simulation apps and share the power and accuracy of COMSOL Multiphysics throughout their organization.

Among the new user-inspired features is the possibility to update graphics while running an app. The app designer can now present app users with different plots while solving, which takes them through the progression of the solution process presenting them, for example, with geometry, mesh, and solution plots. The app designer can now also customize the graphics toolbar with new buttons and include camera movements.

The Application Builder allows companies to communicate across multiple departments, knowing that the simulation expert is able to maintain control, enforce quality standards, and ensure that the results can be trusted.

COMSOL Server™Fosters Collaboration throughout Organizations

All of the new features implemented in version 5.2 of COMSOL Server™ software have been designed to facilitate collaboration between users and departments while simplifying administration tasks. “A new caching function allows applications to start up to five times faster; additionally administrators can now assign a single application to be launched as soon as users log in,” said Ed Fontes, CTO of COMSOL. “These are just few of the many new features and concepts introduced with version 5.2.”

Version 5.2 provides simulations experts with a cutting edge user experience in simulation app design and sharing by integrating highly productive model building, app design, and deployment tools to share their simulation applications with users everywhere.

Extensive Library of Apps Available with Version 5.2

To demonstrate the power of the Application Builder, a plethora of new apps have been added to the extensive Application Libraries showcasing the capabilities of the Application Builder. The Application Libraries include several examples ranging from membrane dialysis to water treatment, thermoelectric cooling to heat exchangers, touchscreen design to magnetic prospecting, piezoacoustic transducer to muffler design, MEMS sensor to pressure vessel.

“With version 5.2 we ship about 50 apps demonstrating the depth and power of the Application Builder and the COMSOL Server,” said Svante Littmarck, CEO of COMSOL. “These apps are meant to provide COMSOL users with examples that can be easily inspected, edited, and used as a starting point for their own applications. We had a lot of fun building these apps and love the new Application Builder functionality! For example, if we take a look at the Mixer app, which ships with the Mixer Module, we are presented with a sophisticated application that can be used to simulate almost any type of mixer without requiring expertise in differential equations or CFD. This takes modeling and simulation to a whole new level!”

This simulation app is intended for the simulation of mixers equipped with axial or radial impellers. For a given geometry, the application computes the efficiency of the mixing process. The vessels, which are available in three different shapes, can also be equipped with baffles and any of eleven different types of impellers.

Hundreds of Updates to COMSOL Multiphysics®, COMSOL Server™ and Add-On Products

Version 5.2 provides several new core functionality features inspired by feedback from the vibrant COMSOL Multiphysics user community. For example, users can now add annotations to 3D and 2D plots. A new tetrahedral meshing algorithm minimizes the need for manual interactions when meshing large CAD models. Mesh Parts are introduced for integrating STL surface meshes and NASTRAN volumetric meshes into the geometry building work flow. The use of selections is expanded upon and can now be used for singling out which parts of a solution that should be used in results processing and visualizations.

Version 5.2 also introduces numerous enhancements to the existing functionalities of COMSOL Multiphysics and its add-on products. Users will benefit from more flexible license management, allowing them to work on their designs knowing that if the connection to the license manager is disrupted they have the option to save their files and resume once a connection is reestablished. Users of the Structural Mechanics Module and the AC/DC Module will benefit from the new External Materials functionality allowing materials to be algorithmically defined by shared library files written in C language. The most prominent use of this new functionality will be for nonlinear materials that include hysteresis (history dependency) and irreversibility effects.
