MSC.Software Enhances Desktop Simulation Portfolio With MSC.visualNastran 4D 2003

New Version of Popular Desktop FEA and Motion Software Gives Engineers Added Functionality

SANTA ANA, Calif. - Dec. 19, 2002 - MSC.Software Corp. (NYSE: MNS), the leading global provider of simulation software, services and systems, today announced the availability MSC.visualNastran 4D 2003. MSC.visualNastran 4D is a Windows®- based virtual product development tool that sets 3D assemblies into motion, animates the resulting stresses and lets mechanical engineers measure the performance of moving components. Engineering organizations can reduce design time and costs by verifying designs with physics-based motion, running preliminary stress analyses and testing control systems all in one complete testing environment.

"There is a growing demand in the market for sophisticated, desktop virtual product development tools," said Frank Perna, chairman and chief executive officer of MSC.Software. "MSC.Software is committed to providing engineers both CAD-embedded and CAD-interfacing simulation products to help them save time and reduce costs. We see this as an important market segment and the newest version of VN4D will help us turn customer demand into revenue."

MSC.visualNastran 4D 2003 addresses the CAD user population that has an estimated market size of approximately $500 million. The newest version of MSC.visualNastran 4D supports virtually every CAD system through associative integration with Autodesk Inventor(tm) & Mechanical Desktop®, Pro/ENGINEER(tm), SolidWorks® and Solid Edge(tm) and through industry standard file formats, such as ACIS, STEP, STL, and Parasolid and CATIA model files.

In addition to analyzing rigid body dynamics, motion-related stress analysis, structural responses such as vibrations, deflection and buckling and providing photo-realistic rendering and animation, MSC.visualNastran 4D 2002 now simulates a broader range of motion applications and is easier to use than ever before. Some of the new features include:

Spherical Joint in Curved Slot Mechanisms: The 'Pin in Slot' is a very common device in mechanical designs. This new feature allows users to define a spherical joint on a curved slot and solve these types of problems faster than ever before.

Clipping Planes: Clipping planes allow engineers to view stress/strain information from section views of the assembly, giving them a unique perspective on what's happening to the element results inside the body they are testing.

Simulation Reports: The new Simulation Report function allows engineers to keep track of each design iteration and test and update the report as they work through the simulation process. This allows users to spend more time engineering and less time writing reports and trying to remember data.

Snapshots: The new 'Snapshot' tool allows users to save pictures of an active modeling window on the fly in jpeg, bitmap or gif format. This gives engineers the opportunity to capture picture documents for reports in real time and not have to recreate them at a later date.

Improved materials database: The material database can now be customized with new materials and temperature-dependent materials, giving users more flexibility and more accurate overall results.

Improved Pro/Engineer Integration: Many MSC.visualNastran4D customers utilize the Pro/Engineer CAD systems. The newest version gives users an improved STEP file translation which improves the geometry transfer and makes it easier to incorporate simulation tools into the design process.

Updated Online Tutorial Guide: All tutorial exercises are now included in an HTML-based system that includes new QuickTime movies.

MSC.visualNastran 4D 2003 is available directly from the MSC.Software sales team, through its worldwide network of resellers and available for monthly licensing via MSC.Software's OnDemand licensing service at
