Abstract: Abstract We present a fast and accurate numerical method to compute unstable micromagnetic configurations. The proposed scheme, which combines various state of the art methods, is able to treat the pointwise unit-length constraint of the magnetization field and to efficiently compute the stray field energy. Furthermore, numerical results are presented which are in agreement with the expected results in simple situations and allow predictions beyond theory.
