摘要简易渐近边界条件是求解开边界问题的一种稀疏但近似的方法。由于该方法将无界空间近似为一系列各向同性壳，因此几乎可以在任何有限元求解器中轻松实现，而无需额外的代码。以前的文件解决了应用这种技术的磁问题描述的矢量位制定。本文将此方法推广到静电学和相关标量势公式。
Improvised asymptotic boundary conditions are a sparse but approximate method of solving open boundary problems. Since this method approximates unbounded space as series of isotropic shells, it can be readily implemented in virtually any finite element solver without the need for additional code. A previous paper addressed application of this technique to magnetic problems described with a vector potential formulation. This paper extends the method to electrostatics and related scalar potential formulations.
