Functions

func DemagKernel

func DemagKernel(inputSize, pbc [3]int, cellsize [3]float64, accuracy float64) (kernel [3][3]*data.Slice)

Calculates the magnetostatic kernel by brute-force integration of magnetic charges over the faces and averages over cell volumes. Mesh should NOT yet be zero-padded.

func MFMKernel

func MFMKernel(mesh *d.Mesh, lift, tipsize float64) (kernel [3]*d.Slice)
