ESI Group has released the 2014 version of its CEM Solutions integrated software environment for virtual prototyping of electromagnetic phenomena. The software suite, says ESI, offers electromagnetic compatibility specialists, equipment designers and systems integrators a solution for integrating hybrid and coupled processes across the electromagnetic spectrum. The company reports that automotive and ground transportation applications received a specific focus in CEM Solutions 2014 and that many additional enhancements target engineers working on aeronautics, defense and marine applications.
ESI describes CEM Solutions as a consolidated software system comprising two of its computational electromagnetics (CEM) applications, PAM-CEM Simulation Suite and Efield Solutions. PAM-CEM Simulation Suite operates mainly within the medium- to high-frequency range. Efield Solutions is frequency-domain oriented with a focus on antennas and scattering. The CEM Solutions suite offers components for such applications as EMC/EMI (electromagnetic compatibility/electromagnetic interference) with cable networks, antenna placement and radar signatures.
CEM Solutions, according to the company, integrates all major computational electromagnetics time and frequency methods within a single framework through Visual-CEM, which is a portion of ESI Group’s multidomain simulation platform. This, explains the company, provides efficient simulation of electromagnetic phenomena using coupled and hybrid techniques, which, in turn, enables fully realistic virtual prototypes.
Updates in CEM Solutions 2014 for the automotive sector include enhanced virtual testing capabilities with a dedicated radio noise process. The company explains that this capability allows engineers to evaluate spurious electromagnetic noise from internal cabling and other emitting components to determine their effects on onboard antennas, receivers and similar devices.
Additional enhancements for engineers in the automotive sector include a multi-scale modeling process that combines standard computational techniques with analytical formations as well as the ability to investigate the performance of 24GHz radar sensors located behind plastic bumpers. CEM Solutions 2014 has also been updated to take into account precise design parameters such as 3D shapes and surface coating, enabling the evaluation of phenomena induced by very thin metallic paint coatings. The company adds that CEM Solutions 2014 can address millimeter-wave (77 GHz) radar sensors used in active safety applications, long-range detection and advanced driver assistance.
CEM Solutions 2014 also offers expanded functionality for engineers working on aeronautics, defense and marine applications. Among these are enhancements for radar absorbing materials used for stealth purposes, multilayer radome structures and other phased array antennas.
The Visual-CEM virtual environment provided with CEM Solutions 2014 has been upgraded to version 9.5. Visual-CEM is actually a part of the company’s Visual-Environment integrated environment for multidomain engineering simulation. Visual-CEM provides you the support for computational engines operating in both time and frequency domains. Additionally, it offers updated 3D polar plots, which are a must for antenna design and scattering studies, according to the ESI Group.
