近年来,对麦克斯韦问题边界积分方程的理论认识有了很大的进展。特别是,稳定的双配对的离散化空间已被开发,允许强大的配方的预处理电场,磁场和组合场积分方程。在BEM++边界元库中,我们开发了这些框架的实现,这些框架允许在几行代码内直观地制定典型的麦克斯韦边界积分公式。这些发展的基础是一个有效的和强大的实现卡尔德龙身份连同产品代数,隐藏和自动化组装Galerkin边界积分方程所涉及的大多数技术。在本文中,我们证明了这个框架,并使用它来获得非常简单和强大的软件配方的标准预处理电场,磁场和正则化的组合场积分方程麦克斯韦。
In recent years there have been tremendous advances in the theoretical understanding of boundary integral equations for Maxwell problems. In particular, stable dual pairings of discretisation spaces have been developed that allow robust formulations of the preconditioned electric field, magnetic field and combined field integral equations. Within the BEM++ boundary element library we have developed implementations of these frameworks that allow an intuitive formulation of the typical Maxwell boundary integral formulations within a few lines of code. The basis for these developments is an efficient and robust implementation of Calderón identities together with a product algebra that hides and automates most technicalities involved in assembling Galerkin boundary integral equations. In this paper we demonstrate this framework and use it to derive very simple and robust software formulations of the standard preconditioned electric field, magnetic field and regularised combined field integral equations for Maxwell.
