路由器的外壳设计 摘 要 一个给定过程的有效模拟需要来自于应用领域(自然科学或工程)、数学(分析和数值数学)及计算机科学的知识。然而，所有这些技术在复杂应用中的使用并不是太容易。这是因为组合所有这些方法需要巨大的复杂性及交叉学科的知识。最终软件的实现变得越来越复杂，以致于超出了一个人能够管理的范围。一些非常成功的解偏微分方程的技术，特别是自适应网格加密（adaptivemeshrefinement）和多重网格方法在过去的十年中已被数学家研究，同时随着计算机技术的巨大进展，特别是大型并行计算机的开发带来了许多新的可能UG NX是一个在二和三维空间无结构网格上使用自适应多重网格方法开发的一个灵活的数值求解偏微分方程的软件工具。其设计思想足够灵活地支持多种离散方案。因此软件可对许多不同的应用再利用 关键词：精度；塑料模； Abstract A given effective simulation of the process of need from the application domain (natural science or engineering), mathematics (analysis and numerical mathematics and computer science knowledge. Use of all of these technologies in complex applications, however, is not easy. This is because the combination of all these methods need great complexity and interdisciplinary knowledge. The realization of the final software is becoming more and more complex, that is beyond the scope of a person can manage. Some very successful solution of partial differential equations of technology, especially the adaptive mesh refinement (adaptivemeshrefinement) and multiple grid method in the past decade has been the mathematicians, at the same time with the huge progress of computer technology, especially the development of large-scale parallel computer brought a lot of new possibilities. UG NX is a grid in two and three dimensional space structure using adaptive multigrid method to develop a flexible software tool for the numerical solution of partial differential equation. Its design idea is flexible enough to support a variety of discrete scheme. So the software can be reused for many different applications. Based process equipment as the main production of plastic products of plastic mold, occupies an important position in national economy, mould technology has become a measure of a country also one of the important symbol of the levels of product manufacturing. Since the 21st century, in the mold industry developing rapidly in our country. Mold industry in order to promote our country a gr
