高端数字样机系统的前处理用户环境

Preprocessing environment in a high end digital prototyping system

前处理是数值模拟的主要性能瓶颈,高端数字样机HEDP(High End Digital Prototyping)系统的前处理用户环境HEDP/Pre包含几何处理、网格密度定义及网格生成等三个模块,结合图形交互式界面等可视交互工具,为满足前处理的诸多共性需求提供了一类适用的解决方案,其有效性已在多领域的数值模拟实践中得到初步验证,对类似软件系统的实现具有参考价值。

A user environment, named HEDP/Pre, has been developed to break the performance bottleneck encountered in the preprocessing step of numerical simulations. Three major modules are Contained in the HEDP/Pre to fulfill the functionalities for geometry modeling,element size specification and mesh generation. The visual steering tools provided by the HEDP/Pre allow the user control and guide each stage of these functionalities. Currently, the capabilities of HEDP/Pre have been validated in some multidisciplinary engineering analyses.
