COMSOL Multiphysics® version 4.0 delivers the COMSOL Desktop, an all-new user interface that makes it easy for users to build and run simulations.

COMSOL Multiphysics Version 4.0 Now Shipping

New breakthrough user interface makes the power of multiphysics simulation available to a wider audience.

BURLINGTON, MA (April 30, 2010)— COMSOL Inc. announces that version 4.0 of its multiphysics simulation software is now shipping. First unveiled at the 2009 users conference in Boston, COMSOL Multiphysics version 4.0 features an all-new user interface that makes the power of multiphysics simulation available to a wider audience of scientists and engineers. Both expert analysts and non-experts alike will benefit from the organized layout and streamlined model-building process. Along with the release of version 4.0, COMSOL also announces the release of a series of new LiveLink™ options that tightly integrate COMSOL Multiphysics into the mainstream product design workflow. New LiveLink products are now shipping for Autodesk® Inventor®, Pro/ENGINEER®, SolidWorks®, and MATLAB®.

“It feels great to make version 4.0 available,” comments Svante Littmarck, President and CEO of COMSOL, Inc. “We believe this release represents a bold step forward in usability that will increase productivity and problem solving capacity.” Version 4.0 is also a platform for accelerating the pace of development of new functionality. “Customers will notice this effect in the very near future: version 4.0a, available this June, includes three new modules for CFD, Plasma, and Batteries & Fuel Cells,” says Littmarck.

COMSOL Desktop - New Breakthrough User Interface

Model set up is smooth and direct, making tough problems quick and easy to solve. Version 4.0 brings an unprecedented level of clarity to product design simulation by combining an organized model overview and a streamlined model-building process in the new COMSOL Desktop. It uses functional form, structure, and aesthetics as the means to achieve simplicity for modeling complex physical realities. For instance, task-specific tools appear on the Desktop right when you need them and show only the currently possible and necessary actions. This helpful user convenience removes uncertainty from model building and brings order to simulations.

ZINK Imaging, the inventor of the ZINK Technology and the manufacturer of ZINK Paper™ -- a revolutionary approach to full-color printing of information and images with unparalleled simplicity -- makes frequent use of COMSOL Multiphysics within product invention, development, and manufacturing. Dr. Bill Vetterling, Research Fellow and Director of the Image Science Lab at ZINK Imaging, attended the 2009 COMSOL Conference and tried out the new user interface. "The version 4.0 prerelease that was made available to attendees was a great way to try out new features,” says Dr. Vetterling.

“Version 4.0, by the way, is a masterpiece! It was a special treat this year to explore its fresh, new interface and insightful approach to the overall management of data,” adds Dr. Vetterling. "In my experience, COMSOL Multiphysics is a product that makes significant advances year after year."

LiveLink family of products for integrating with CAD, MATLAB

By adopting COMSOL simulation, CAD software users can now accurately simulate how real-world physical effects shape the design of new products. To this end version 4.0 features the optional LiveLink family of products. Each LiveLink connects COMSOL Multiphysics directly with leading CAD programs so that all parameters specified in a CAD model can be interactively linked with simulation geometry. The current product line includes LiveLink™ for SolidWorks®, LiveLink for Inventor®, and LiveLink for Pro/ENGINEER®. In addition, LiveLink for MATLAB® is available for those who need to incorporate a COMSOL Multiphysics model into an extended technical computing and programming environment.

COMSOL Multiphysics on Windows HPC Server 2008

COMSOL Multiphysics version 4.0 now runs on Windows HPC Server 2008, creating a scalable and affordable high performance computing solution for simulation and virtual prototyping. Current users with a COMSOL Multiphysics version 4.0 floating network license will be able to deploy across as many Windows HPC Server 2008 nodes as they choose, at no additional COMSOL Multiphysics licensing cost.

“By creating applications that run on Windows HPC Server 2008, scientific and engineering software companies like COMSOL are helping speed discovery”, said Vince Mendillo, senior director, Microsoft High Performance Computing Group. “ Scientists, engineers and analysts need easy-to-use tools and accessible high performance computing power to create competitive advantage.”

COMSOL Multiphysics supports parallel processing through standard shared-memory multicore computers as well as distributed-memory clusters. Users can turn to clusters to solve a series of parameter steps for a model, one parameter per node, or they can solve a single large model using distributed memory. For maximum performance, the COMSOL cluster implementation can utilize shared-memory multicore processing on each node in combination with the MPI-based distributed memory model.
