Shape Optimization of Homogeneous Electromagnetsmogeneous as possible. This is generated by so-called homogeneous electromagnets. The optimization aims at the optimal shape of the pole heads. The governing linear magnetostatic problem is approximated by the Finite Element Method (FEM) where quadratic triangular elements or edge elements are used

Calculation of Electromagnetic Eigenmodes in Complex Structures Using Coupled S-Parameter Calculatio, the application of these solvers is limited even on the most powerful workstations by the available computational resources in terms of memory and computation time. This paper will present a technique based on scattering parameters that allows to split the complete geometry into subsections which

Multigrid Solvers for Poisson’s Equation in Computational Electromagneticsthe related equations. In the present paper we investigate multigrid algorithms for the solution of static problems on adaptive discretizations. Two multigrid strategies are compared: algebraic multigrid, which performs the adaption to the discretization automatically and geometric multigrid with se

Field Calculations of High Accuracy by BEM Using Extrapolationle by extrapolating a set of two or more calculations with increasing number of elements. For a spherical condensor and a magnetic lens we can demonstrate, how even artifacts, originating from insufficient numerical analysis, are suppressed by the extrapolation technique.
