PAM-CEM SOLUTIONS REDUCES PHYSICAL TESTS IN AUTOMOTIVE ELECTROMAGNETIC COMPATIBILITY
30 March 2004 - ESI Group

ESI Group today launched PAM-CEM Solutions 2004, a comprehensive family of software for virtual testing of complex electromagnetic phenomena. PAM-CEM Solutions 2004 analyzes electromagnetic compatibility and interference problems in a wide frequency range. PAM-CEM Solutions includes CRIPTE, for induced phenomena on cable networks, and SYSMAGNA, for low frequency analysis.

PAM-CEM Solutions 2004 meets automakers' requirements for a fully realistic Electromagnetic Susceptibility analysis in the early design stage, including simulation of 3D radiated fields and induced effects on the vehicle cable networks. With the proliferation of complex on-board electronic equipment throughout the transportation industry, controlling electromagnetic disturbance is more critical than ever to meeting performance and security objectives.

This new release is a real breakthrough towards the deployment of digital Electromagnetic Compatibility in the automotive industry. Only a close collaboration between ESI Group and leading car manufacturers such as Renault or Nissan could make it happen, says Jean-Claude Kedzia, PAM-CEM Solutions product manager. PAM-CEM Solutions gives EMC experts the ability to manage very sophisticated cable networks. Complex electromagnetic phenomena can be investigated in depth very early, long before the first physical EMC prototype is available. The results of simulations powered by PAM-CEM Solutions provide a better understanding of how the car will perform, helping engineers to evaluate rapidly various options in the vehicle electrical design.

With the new release, time domain radiated fields can be either calculated through finite difference algorithms for fast evaluation, or accurately computed using advanced modeling with 3D finite element formalism. Both options are automatically coupled with CRIPTE.

Antenna radiation simulation is one of the main areas where PAM-CEM Solutions 2004 brings full understanding of the phenomena. Several levels of accuracy are available to the user for the analysis of wired antennas. For example, the expert can select a fast evaluation to optimize the performance of traditional antenna devices and their location on-board, while an accurate simulation will be required to analyze sophisticated rear or side window antennas, which are known to be sensitive to their operating environment.

Other new features of the 2004 release include a user-friendly environment with enhanced modeling capabilities for on-board antennas and cable networks, from their placement in the vehicle to the specification of the related electrical architecture.

About: ESI Group
ESI Group is the world leading software editor for the numerical simulation of prototype and manufacturing process engineering in applied mechanics. The key to ESI Group's success is the use of realistic material physics, providing "as good as real" virtual solutions, in order to replace the lengthy trial and error processes on real prototypes.

ESI Group has developed an entire suite of coherent industry-oriented applications to realistically simulate a product's behavior during testing, to fine tune the manufacturing processes in synergy with the desired product performance, and to evaluate the environment's impact on product usage. ESI Group's product portfolio, which has been industrially validated and combined in multi-trade value chains, represents a unique collaborative, virtual engineering solution, known as the Virtual Try-Out Space (VTOS), enabling a continuous improvement on the virtual prototype.

By drastically reducing costs and development lead times, VTOS solutions offer major competitive advantages by progressively eliminating the need for physical prototypes.

A sustained growth

Total consolidated revenue for fiscal year 2003, ending January 31st 2004, increased by 15% in real terms and 22% at constant exchange rates, compared to the previous year reaching 49 million euro.

The software activity remained stable with 73% from licenses and 27% from services.

The major acquisitions made in 2002 and 2003 accounted for 15% of revenue growth and took part in the strengthening of the Group's position on the American market.

As in previous years, ESI Group maintained a strong international presence with 50% of turnover generated outside Europe and 79% of revenue outside.

Listed on the Nouveau Marché of Euronext Paris, ESI Group employs almost 500 high-level specialists worldwide.
ESI Group and its global network of agents provide sales and technical support to customers in more than 30 countries.

A key investment area: Research and Development

ESI Group is making substantial R&D efforts and forms partnerships with leading academic and research laboratories in order to offer state-of-the-art solutions.

ESI Group also provides high value-added services, worldwide through its subsidiaries located in Europe, Asia and Americas. Consulting projects with strategic industrial partners as well as European R&D contracts exemplify ESI Group's strong engineering knowledge and scientific expertise.
