MagTense: A micromagnetic framework using the analytical demagnetization tensor

We present the open source micromagnetic framework, MagTense, which utilizes a novel discretization approach of rectangular cuboid or tetrahedron geometry "tiles" to analytically calculate demagnetization field. Each tile is assumed be uniformly magnetized, and from this assumption only, field can calculated. Using we solution mmag standard problems 2, 3 4 find that MagTense framework accurately predicts each these. Finally, show simulation time significantly improved by performing dense tensor matrix multiplications using NVIDIA CUDA.
