The design and verification of Mumax3
摘要：
我们报告的设计，验证和性能的mumax3，一个开源的GPU加速微磁模拟程序。该软件使用有限差分离散化解决了纳米到微米尺度磁体中的时间和空间相关的磁化演化。它的高性能和低内存要求允许在有限的时间和廉价的硬件上进行大规模的仿真。我们通过将结果与可用的分析值和微磁标准问题进行比较来验证软件的每个部分。mumax3还提供了特定的扩展，如MFM图像生成，移动模拟窗口，边缘电荷去除和材料颗粒。
英文摘要：
We report on the design, verification and performance of mumax3, an open-source GPU-accelerated micromagnetic simulation program. This software solves the time- and space dependent magnetization evolution in nano- to micro scale magnets using a finite-difference discretization. Its high performance and low memory requirements allow for large-scale simulations to be performed in limited time and on inexpensive hardware. We verified each part of the software by comparing results to analytical values where available and to micromagnetic standard problems. mumax3 also offers specific extensions like MFM image generation, moving simulation window, edge charge removal and material grains.
