Simulation will Support Car, Light Truck and Powertrain Development

Leuven, Belgium - April 2, 2003 - LMS International announced today that
Renault is investing in a multiple installation of LMS Virtual.Lab virtual
prototyoping software for engine acoustics to support their powertrain and
vehicle engineering activities. Convinced of its capability and reliability,
Renault is implementing leading edge LMS acoustic simulation technologies in
their mainstream development proces. LMS Virtual.Lab will increase the
efficiency of Renault's acoustic modeling and computation procedures, and
will reduce the time and cost of their design processes.

Vehicle refinement and vibro-acoustic comfort have always been important in
Renault's strategy of developing distinctive and superior vehicles. To
achieve higher levels of acoustic comfort within shorter development times,
Renault began to explore how to address acoustic performance early in the
process. Renault's involvement in the development of LMS Virtual.Lab
convinced them that this was the solution they had been looking for.

LMS Virtual.Lab Acoustics dramatically accelerates the acoustic modeling
process at Renault. Creating an acoustic mesh starting from a structural
model used to be a lengthy, manual process. LMS Virtual.Lab applies a
completely new meshing method. It "wraps" a structural FE model and reduces
the amount of detail to the level needed for the acoustic simulation. The
smaller size of the model means that acoustic calculations are much faster
than before, and that more designs can be evaluated.

Renault also chose LMS Virtual.Lab for its improved acoustic solver. It
delivers fast, efficient calculations that are especially useful for
multiple engine speeds, and for assessments of the complete engine during
run-up. The LMS Virtual.Lab solver is so fast that acoustic simulations will
now become a regular part of the development process at Renault.

With LMS Virtual.Lab, Renault will be able to quickly assess the virtual
behavior of their engines because of the easy mesh preparation and the
effectiveness of the acoustic calculations. Renault engineers liked the
quality and the integration of the functions and tools - covering the
complete engine vibro-acoustic process - as well as the sheer speed of the
re-meshing and simulation steps. M. Bernard, head of Renault's "Direction de
la Recherche" (Research Department) stated: "LMS Virtual.Lab has reduced the
time we used to waste in converting from a structural to an acoustic
powertrain model, from several days per model, down to a few hours."

About LMS Virtual.Lab

LMS Virtual.Lab is the world's first integrated software environment for the
functional performance engineering of critical design attributes, such as
noise and vibration, ride & handling, comfort, safety & durability. Fully
associative, it automatically links to leading CAD and CAE tools, captures
the process flow to better manage the analysis sequence, and enables
engineers to refine their designs in virtual space not just at the component
level - but also at the sub-assembly and full system level where most
performance problems occur. By eliminating unnecessary file transfers,
model and data redundancies, and automating the analysis process, LMS
Virtual.Lab dramatically increases the time available for value-added
engineering. LMS Virtual.Lab is based on CAA V5 (Component Application
Architecture), the open middleware for PLM from Dassault Syst譥s.
