Overview
Numerical methods for solving low frequency electromagnetic field problems—many of which refer to eddy currents appearing in various electromagnetic devices—have been developed and utilized with increasing success in recent years. Originally such problems were tackled by analytical solutions limited to simple geometries and linear materials. In practice, however, all electromagnetic devices have complex boundaries, include non-linear materials, and may be treated exclusively by numerical methods. This book provides a systematic, mathematical simulation of existing methods and discusses the discretization of relevant equations. Methods described include finite difference, finite sums, finite element, boundary element, and some variants. Physical connotations of methods and problems are also given. Written by top experts in the field, this book fills the need among professional electrical engineers and graduate students for both a theoretical and practical approach to this important topic.
