COMSOL announces the 4.3 release of COMSOL Multiphysics, its industry-leading software environment for modeling and simulating any physics-based system. COMSOL Multiphysics 4.3 empowers engineers, researchers, and scientists with powerful new modeling tools and fast simulations that further establish COMSOL as a leading innovator in simulation for electrical, mechanical, fluid flow, and chemical applications. Major new capabilities introduced in version 4.3 include three new discipline-specific add-on modules, fast and powerful meshing, a new solver for mechanical contact and highly nonlinear simulations. With the debut of three new discipline-specific add-on modules – the Nonlinear Structural Materials Module, the Pipe Flow Module, and the Corrosion Module – COMSOL now offers 30 products for the simulation of multiphysics phenomena.

User-inspired Developments
COMSOL users played a vital role in developing this new version. Their requests, suggestions, and feedback contributed significantly to the features that were ultimately implemented.

“Our mission is to bring engineers and scientists reliable simulation tools that impact their day-to-day work, so their input is a crucial component of our product,” said Bjorn Sjodin, VP of Product Management for COMSOL. “We’re continually soliciting and receiving feedback from our user base, while pursuing that passion for innovation that COMSOL is known for.”

Version 4.3`s modules for electrical, mechanical, fluid flow, and chemical simulations have all been updated with new features and capabilities. Responding to multiple requests, COMSOL implemented a user interface within the AC/DC Module for modeling 3D rotating machinery. Users of the Structural Mechanics and MEMS Modules will appreciate a new solver for mechanical contact and highly nonlinear simulations – the “Double Dogleg” solver. The CFD Module introduces new, easy-to-use interfaces and added functionality for mass transport simulations influenced by turbulent mixing, while the Particle Tracing Module now incorporates particle-particle interaction and Brownian forces into its extensive list of supported functionalities.

This May, corrosion experts gathered at the COMSOL headquarters in Burlington, MA, to be the first to put their hands on the Corrosion Module. “I am new to COMSOL Multiphysics, and I made the decision to become a user with the debut of the Corrosion Module,” says Staff Research Engineer Lei Chen with UTRC, Hartford, CT.
