基于面向对象的非线性瞬态电磁场快速算法

A Fast Algorithm of Nonlinear Transient Electro-magnetic Fields Based on OOP Technique

针对求解非线性瞬态电磁场问题数据量大、速度慢的缺点,以及商业软件对研究的自主性、深入程度的制约,基于数据结构的基本原理,采用面向对象(OOP)和组件(COM)技术,提出了一种非线性瞬态电磁场问题求解的快速算法,将ICCG法、N—R法求解等过程和稀疏矩阵的构建紧密耦合,大大提高了计算速度,并易嵌入到其他软件中。仿真计算表明,该方法是有效的,且适合于工程及科研应用。

There are some problems such as large data size and long CPU time in solving nonlinear transient electromagnetic field, and commercial softwares do not support users to make their own study on their will and more deeply. Based on the basic theory of data structure, OOP and COM technology are adopted to present a fast method to solve nonlinear transient electromagnetic field. The ICCG method and N -R method are coupled closely with the sparse matrix, which saves much CPU time and makes it easy to be embeded into other software. Simulating calculation proves that the method is effective and more suitable for engineering and research application.
