Computational Electromagnetism: Variational Formulations, Complementarity, Edge Elements
Computational electromagnetism begins where electromagnetic theory stops, and stops where engineering takes over. Its purpose is not to establish Maxwell equations, and other essential physical theories, but to use them
in mathematical modelling, with concrete problems in view.
Modelling is this activity by which questions about a physical situation are translated into a mathematical problem—an equation, if this word is understood is a general enough sense—that will be solved, in order to answer these questions. “Solving”, nowadays, means using a computer, in most cases. The equations one aims at, therefore, can very well be huge systems of linear equations (solved as part of some iterative process, in nonlinear situations, or in the simulation of transient phenomena). Complex shapes, non-uniform physical characteristics, changing configurations, can and should be taken into account. Adequate methods—not necessarily the exclusivity of electromagnetics—have been developed for this: finite elements, boundary integral methods, method of moments . . . Strengthening their foundations, clarifying their presentation, enhancing their efficiency, is the concern of computational electromagnetism.
