The 2002 version of PAM-CEM Solutions from ESI Group includes many new features for the realistic virtual testing of complex electromagnetic phenomena.

From the influence of electronic devices in the transportation industry - automotive and railway - to telecommunications and antenna design, PAM-CEM Solutions 2002 analyses electromagnetic compatibility and interference problems.

PAM-CEM Solutions 2002 enables manufacturers to streamline the product development process, making engineering environments more productive.

The new enhanced user environment reduces the implementation phase and allows the user to focus on the analysis.

Most native CAD data can be imported using the Geomesh module, while existing mesh from Nastran, DXF or STL, can be directly handled through the enhanced "discrete surface" feature.

The related meshing stage is improved as well, with refinement capabilities in close relationship with significant electromagnetic contributors such as, wire antennas, slots, or apertures.

Fully integrated into the Virtual Try-Out Space (VTOS), PAM-CEM Solutions 2002 includes PAM-CEM 2002, an advanced 3D finite element simulation tool for electromagnetic compatibility, CEM3D, a solver for fast evaluation of radiated electromagnetic fields, Cripte, a tool for interference analysis on cable networks, and Sysmagna, a dedicated software product for low frequencies.

"PAM-CEM Solutions 2002's new features will allow the deployment of advanced CEM simulation in the automotive industry, and help evaluate onboard communications devices existing in the newest generation of vehicles - including telephony, navigational aides and information systems - and their impact on electromagnetic compatibility", says Jean-Claude Kedzia, PAM-CEM Solutions Product Manager, ESI Group.

Key features include: modelling of dielectric materials that provides more detailed analysis, featuring parasitic effects of automotive internal equipment, such as windows, glass components, or joints.

Antenna design with multi-frequency analysis gives direct access to radiation patterns in the complete operating frequency range in one single run, drastically reducing computational time.

Rectilinear and circular polarisation of radiated waves can now be handled, fulfilling typical industrial requirements for antenna design.

Several postprocessing capabilities are now available: input or transfer impedance management, Smith charts, radiation patterns, either in 2D polar plots or in the entire 3D space etc.

Pam-Cem Solutions 2002 are available on Unix workstations and servers from Compaq, HP, IBM, NEC, SGI and Sun.
