在电力系统的数值模拟中，离散模型和无网格模型经常同时使用，例如在粒子单元（PIC）代码中。本文的目的是介绍新的插值技术，以及在不规则四点网格的本地化。这些算法将现有的规则网格的方法推广到由非等距凸四点网格组成的网格。它们的开发是为了获得较短的CPU时间和可能的矢量化。
In numerical simulations of power systems; discrete models and mesh-free models are very often used simultaneously, for example, in particle-in-cell (PIC) codes. The aim of this paper is to introduce new techniques for interpolation as well as for localization in irregular fourpoint meshes. These algorithms extend the existing, methods for regular grids to grids consisting of non-equidistant convex four-point meshes. They were developed in order to obtain short CPU times and possible vectorization.
