title = "H-matrix techniques for stray-field computations in computational micromagnetics",

abstract = "A major task in the simulation of micromagnetic phenomena is the effective computation of the stray-field H and/or of the corresponding energy, where H solves the magnetostatic Maxwell equations in the entire space. For a given FE magnetization M-h, the naive computation of H via a closed formula typically leads to dense matrices and quadratic complexity with respect to the number N of elements. To reduce the computational cost, it is proposed to apply H-matrix techniques instead. This approach allows for the computation (and evaluation) of H in linear complexity even on adaptively generated (or unstructured) meshes.",
