As indicated by the wide-spread use of computers, demand for numerical simulation of physical phenomena has been rapidly increasing.The purpose of this project is to develop a high-level software package for optical and electromagnetic wave problems. The software package developed here consists of three packages tackling the preprocessing, solving, and post-processing in turn. The solver unit has been integrated with user-friendly mesh generation (pre-processing) and graphics (post-processing) packages for realistic application to practical problems. Results obtained are as follows:1. To preserve the generality of the solver, a numerical approach based on the finite-element method has been developed. 2. The preprocessor has been developed to define the problem geometry, enter nodes, generate elements, and specify material properties - all interactively. The post-processor has also been developed to give a better physical picture. 3. An improved finite-element method without spurious solutions has been developed for the analysis of optical waveguides. A software package for the analysis of optical waveguides has been developed on an EWS (engineering workstation).

正如广泛使用计算机所表明的那样，对物理现象的数值模拟的需求已迅速增加。该项目的目的是为光学和电磁波问题开发高级软件包。此处开发的软件包包括三个软件包，可以依次解决预处理，解决和后处理。该求解器单元已与用户友好的网格生成（预处理）和图形（后处理）软件包集成在一起，以实现实际问题的现实应用。获得的结果如下：1。为了保留求解器的一般性，已经开发了基于有限元方法的数值方法。 2。已经开发了预处理器来定义问题的几何形状，输入节点，生成元素并指定材料属性 - 所有这些都可以交互作用。后处理器也已经开发出来，以提供更好的物理情况。 3。已开发了一种没有伪溶液的有限元方法，用于分析光学波导。在EWS（工程工作站）上已经开发了用于分析光学波导的软件包。
