计算流体力学（CFD）正越来越多地用于模拟建筑内部环境中的通风空气分布。随着高性能计算的成熟，解决工业规模问题的能力出现了。本文介绍了一个500万节点的工业设施混合通风流场CFD预测的设计和解决方案充分性评估。两层楼高的厂房占地面积近似于一个足球场，内部包含100多个几何/热实体，需要详细的网格定义。仿真设计决策和软件选择导致非正规块网格的构建，区域分解用于并行执行。本文详细介绍了模拟决策过程，并解释了生成的解决方案的流程细节和解决方案质量评估。单位:双引文:研讨会论文，大西洋城，2002年

Computational fluid dynamics (CFD) is gaining use in simulating distributions of ventilation air in building interior environments. As high-performance computing matures, the ability to address industrial-scale problems emerges. This paper presents design and solution adequacy assessments for a five million node CFD prediction of the mixed ventilation flow field in an industrial facility. The two-story plant footprint approximates a football field, and the interior contains over 100 geometrical/thermal entities requiring detailed meshing definition. Simulation design decisions and software selections lead to construction of a nonconformal block meshing, domain-decomposed for parallel execution. The paper details the simulation decision process and interprets the generated solution for flow details and assessments of solution quality.Units: Dual
