COMSOL Multiphysics Version 4.3

COMSOL announces the 4.3 release of COMSOL Multiphysics, its industry-leading software environment for modelling and simulating any physics-based system. COMSOL Multiphysics 4.3 empowers engineers, researchers, and scientists with powerful new modelling 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 "Double Dogleg" solver for mechanical contact and highly nonlinear simulations, and numerous user-inspired enhancements. COMSOL Multiphysics 4.3 is available immediately from COMSOL sales offices worldwide.

Enhancements and upgraded functionality span the entire COMSOL product suite. 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. The newest modules expand the COMSOL Multiphysics simulation platform with all-new user interfaces that help users solve the unique design challenges in each of these areas accurately and efficiently.

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, making COMSOL Multiphysics 4.3 a true community effort.

"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."

The combined talent of COMSOL developers and users not only make this a major release, but many of the requested enhancements further increased the integration of COMSOL Multiphysics with the larger CAE community. For example, core modelling capabilities in version 4.3 have been updated and expanded significantly. Meshing is now both faster and more powerful, particularly when working with virtual geometry operations for shielding the automatic mesher from unnecessary geometric detail. Users working with imported meshes can now group existing mesh elements into new domains and boundaries, which makes it easy to assign boundary conditions and material properties wherever desired.

Users can now run multiple-parameter sweeps with easy specification of one, two, or more parameters - sweeping for all of them or just a subset of them. Visualizations of results from these parameter sweeps can be easily selected to include combinations of the swept parameters in a single presentation. New Cluster Sweep and Batch Sweep user interfaces facilitate defining massively parallel and independent parametric sweeps.

Version 4.3's modules for electrical, mechanical, fluid flow, and chemical simulations have all been updated with exciting new features and capabilities. Responding to multiple requests, COMSOL implemented a user interface within the AC/DC Module for modelling 3D rotating machinery. Users benefiting from this new functionality include those working on applications for generators, brushless motors, radial and axial flux machinery along with brushed DC electric motors.

Users of the Structural Mechanics and MEMS Modules will appreciate a new solver for mechanical contact and highly nonlinear simulations -- the "Double Dogleg" solver. New tools for tagging load cases have also been included for easier setup of extensive structural mechanics studies.

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.
