PAM-CEM solutions reduces physical tests in Automotive Electromagnetic Compatibility

ESI Group : 30 March, 2004  (New Product)
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.
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.
