Comsol Multiphysics v4.3 With Update 1 | 4.76 GB
COMSOL Multiphysics version 4.3 contains many new functions and additions to the COMSOL product suite. We have strived to achieve backward compatibility with the previous version and to include all functionality that is available there. COMSOL 4.3 is compatible with COMSOL 3.5a, COMSOL 4.0, COMSOL 4.0a, COMSOL 4.1, COMSOL 4.2, and COMSOL 4.2a with a few exceptions.

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 “Double Dogleg” solver for mechanical contact and highly nonlinear simulations, and numerous user-inspired enhancements.

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 accuratel.

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.

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 modeling 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 modeling 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.

Nonlinear Structural Materials Module

The new Nonlinear Structural Materials Module augments the mechanical capabilities of the Structural Mechanics and MEMS Modules by adding nonlinear material models. When the mechanical stress in a structure becomes large, certain nonlinearities in the material properties force the user to abandon linear material models. This situation also occurs in some operating conditions, such as high temperature. The new module adds elastoplastic, viscoplastic, creep, and hyperelastic material models. These are based on a new, extended framework for the constitutive laws which users can easily extend for their unique needs.

Pipe Flow Module

The new Pipe Flow Module will interest engineers who design and optimize the pipe and channel networks used in turbines, building ventilation systems, chemical and material manufacture processes, and in the oil and gas industry. The module enables efficient simulations of 1D fluid flow, heat and mass transfer, hydraulic transients, and acoustics. The Pipe Flow Module's simulation results can be integrated into 2D and 3D models of network components, yielding the velocity, pressure variation, and temperature along the pipes and channels in the network.

Corrosion Module

Corrosion is everywhere and is an especially important concern for off-shore structures, ships and submarines, aerospace, and automotive parts. George F Hays, Director General of the World Corrosion Organization, estimates that 3% of the world’s GDP is lost every year due to corrosion.

The new COMSOL Corrosion Module offers specialized user interfaces to model the electrochemical processes that lead to corrosion. Using the Corrosion Module, engineers who want to mitigate these processes can gain powerful insights into how structures might corrode under certain conditions and how structures can be protected. The module includes the physics required to model galvanic, pitting, and crevice corrosion as well as cathodic and anodic protection.

Empowering COMSOL Users with More Speed and New Modeling Tools

COMSOL Multiphysics version 4.3 is a major release. It has been built with the combined knowledge and experience of COMSOL's development teams and hands-on practitioners of modeling and simulation from around the world. With its three new expansion modules, this version also empowers users in major industries for the first time with the innovation potential of an easy-to-use yet powerful multiphysics simulation platform that operates the way they think. COMSOL Multiphysics version 4.3 delivers its users simulation products for boosting engineering efficiency.
