| Research Abstract |
This paper describes an evaluation of electromagnetic compatibility based on a full-wave analysisof electromagnetic fields using a parallel finite element method with the balancing domaindecomposition method. The environment chosen is the interior of a commuter train. A traincontaining seats, handrails and 48 human bodies is precisely modeled using a large-scale finiteelement mesh with Nedelec elements and about 21 million degrees of freedom. The results showthat the environmental impact of electromagnetic fields due to cellular phone use in the train can besuccessfully evaluated. And, this paper describes large-scale full-wave analysis of electromagneticfields by the finite element method with an iterative domain decomposition method usingnumerical human body models. A stationary vector wave equation for the high-frequencyelectromagnetic field analysis is solved taking an electric field as an unknown function. The meshis efficiently divided by using the domain decomposition data structure when elements aregenerated from the voxel data of NICT numerical human body model.
