"Fast stray field computation on tensor grids";
Journal of Computational Physics,
A direct integration algorithm is described to compute the magnetostatic field and energy for given magnetization distributions on not necessarily uniform tensor grids. We use an analytically-based tensor approximation approach for function-related tensors, which
reduces calculations to multilinear algebra operations. The algorithm scales with N^(4/3)for N computational cells used and with N^(2/3)(sublinear) when magnetization is given in canonical tensor format. In the final section we confirm our theoretical results concerning computing times and accuracy by means of numerical examples.
