一个并行有限元微磁学软件包已经实现，这是高度可扩展的，易于移植，并结合不同的微磁方程的求解器。实现是基于标准的Galerkin离散四面体网格与线性基函数。一个静态的能量最小化，一个动态的时间积分，和轻推弹性带方法已经实现。详细的实施和优化的一些方面进行了讨论，并给出了时间和加速结果。用该微磁学软件包研究了坡莫合金纳米点的成核和磁化反转过程。(C)2003 Elsevier B.V.保留所有权利。
A parallel finite element micromagnetics package has been implemented, that is highly scalable, easily portable and combines different solvers for the micromagnetic equations. The implementation is based on the standard Galerkin discretization on tetrahedral meshes with linear basis functions. A static energy minimization, a dynamic time integration, and the nudged elastic band method have been implemented. The details of the implementation and some aspects of the optimization are discussed and timing and speedup results are given. Nucleation and magnetization reversal processes in permalloy nanodots are investigated with this micromagnetics package. (C) 2003 Elsevier B.V. All rights reserved.
