After scientists, engineers or educators create a multiphysics model or simulation using FEMLAB, they can share their results with colleagues anywhere, at no charge, with this cross-platform tool for Windows, Linux and Macintosh. It also serves as a valuable tool in the academic environment.

Stockholm, Sweden (July 02, 2004) - The Multiphysics Viewer lets any researcher, scientist or engineer examine, postprocess and visualize results from physics models created by users of FEMLAB software. COMSOL distributes the Multiphysics Viewer, which runs on Windows, Linux and Macintosh OS X platforms, free of charge. Once users open a FEMLAB model, the package allows them to examine settings such as the underlying partial differential equations (PDEs) and boundary conditions. The software also offers flexible postprocessing capabilities such as playback of model simulations, visualization of results and the creation of animations.

“With the Multiphysics Viewer, users can share their models and results with all of their colleagues quickly and at no expense,” comments Bernt Nilsson, VP of Marketing at COMSOL. “Even better,” he adds, “this cross-platform concept allows FEMLAB users to create models on any major platform, while others can examine these models on either Windows, Linux or Macintosh OS X.”

Without requiring the full FEMLAB package, colleagues of FEMLAB users can examine the underlying problem setup, including preprocessing and solver settings, and then review solution results. They can interactively plot model variables and properties using several plot types including slices, isosurfaces, contours, streamlines, deformed shapes, height, boundaries and arrow/vector fields. Additionally, cross-section and domain plots project a solution variable along surfaces and subdomains. Those using the Multiphysics Viewer can also generate time-evolution plots in any model domain, even at points or across user-defined lines and planes. Other routines make it possible to integrate quantities along boundaries and subdomains such as computing force and electric currents. As an aid to presenting results, the tool creates animations based on AVI and QuickTime movie formats.

"We are developing surgical instruments and need to distribute modeling results across teams,” says David Lockwood of Smith & Nephew. "With the Multiphysics Viewer, we can now send them the model, which they can examine in great detail."

The Multiphysics Viewer is compatible with any model created in FEMLAB 3.0 or 3.0a. The utility is available on a CD in versions that run on Windows, Linux or Macintosh OS X. Included on the CD are a tutorial and a number of predefined models.

FEMLAB - which stands for Finite Element Modeling Laboratory - is an advanced software package for the modeling and simulation of any physical process described with PDEs. The latest version, FEMLAB 3.0a, features high-performance, state-of-the-art solvers that address extremely large problems yet quickly yield accurate results. Working in an easy-to-use graphical interface or from a command line, users choose from several ways to describe their problems in 1D, 2D, and 3D. A particular strength of the package is its PDE modeling capability, enabling equations from various fields such as structural mechanics, electromagnetics, fluid flow, and chemistry to be linked and solved all in the same model and all at the same time. These and many other features make FEMLAB 3.0a an unprecedented modeling environment for research, product development and education.

Founded in 1986 in Stockholm, Sweden, COMSOL has grown to include U.S. offices in Burlington, MA, and Los Angeles, CA. Internationally the firm has operations in Denmark, Finland, Norway, Germany, France and the United Kingdom. Full details about the company and its products are available at www.comsol.com.
