A Complete Environment for Computational Electromagnetics (CEM)

CEM One is a consolidated CEM software package with its first commercial shipment in December 2012, combining the best of Computational Electromagnetics, namely PAM-CEM Simulation Suite and Efield Solutions.

PAM-CEM Simulation Suite operates mainly from medium to high frequency range. When targeting a wide frequency spectrum, as usually managed with EMC/EMI issues, time-domain techniques are applied to investigate electromagnetic phenomena appearing along those complex cables networks connecting onboard electronics.

Efield Solutions is primarily frequency-domain orientated with focus on antennas and scattering, making the overall solution fully consistent. ESI acquired Efield at the end of 2011.

A Complete Environment for Computational Electromagnetics (CEM)

The consolidated CEM solution emphasizes a coupling and hybridization strategy, extending well beyond previous limits with larger models, higher operating frequencies and more sophisticated scenarios, taking electromagnetic modeling one step further.

Visual CEM

Visual-CEM is a part of ESI’s virtual prototyping platform – Virtual Integration Platform.

Virtual Integration Platform is a process orientated engineering approach which is able to solve multiple problems at a time. It is a single environment with a capacity to not just chain several simulation designs and results but, also, to bring them into fully customized models suiting customer demands.
