The fundamental goal of this research is the development of the science base necessary to reduce the time and effort required to assemble and use computer tools for simulation and analysis of physical systems. Most existing simulators solve a limited range of problems, are difficult to modify, and are difficult to integrate because each uses its own representation scheme. The research will address these issues and build an environment that automates many of the steps in creating a simulator. Defining a simulator requires; choosing equations to model the behavior of the physical systems, choosing and implementing computational methods for solving the equations defining mechanisms to handle the complex control flow of simulations, and choosing representation schemes for physical objects, their properties, equations, etc. Currently, these steps are carried out implicitly, without computer aid. The researchers will design a software architecture that allows simulators to be described in terms of equations and mathematical properties naturally suited to the problem. The research will develop: a model representation system for representing the quantities and laws that describe the physical behavior in a given analysis model; and analysis specification system, a language for defining the behavior of a simulation in terms of the laws and quantities; a scene editor; and a low level interface for integrating existing modules such a numerical packages or finite element codes.

本研究的基本目标是开发 科学基础，以减少所需的时间和精力， 组装和使用计算机工具进行模拟和分析， 物理系统。 大多数现有的模拟器解决了有限范围的 问题，难以修改，难以整合 因为每个都使用自己的表示方案。 这项研究将 解决这些问题，并构建一个环境， 创建模拟器的步骤。 定义一个模拟器需要;选择方程来模拟 物理系统的行为，选择和实施 求解机构方程的计算方法 处理模拟的复杂控制流，并选择 物理对象的表示方案，它们的属性， 方程等。 目前，这些步骤是在没有计算机的情况下隐式地进行的。 援助 研究人员将设计一个软件架构， 允许用方程描述模拟器， 数学性质自然适合的问题。 的 研究将开发：模型表示系统， 代表描述物理的量和定律 给定分析模型中的行为;以及分析规范 系统，一种用于定义仿真行为的语言， 法律和数量的条款;场景编辑器;和低水平 用于集成现有模块的接口，例如数字包 或有限元代码。
