| 摘 要： | CFD和FEA方法一样是结合数值计算、计算机技术和工程建模而产生的新兴学科．该方法在实际运用中分为前处理、求解和后处理三个阶段．前处理核心是几何建模、块和网络生成．几何建模要建立静态几何模型和动态几何模型．块生成要体现其区域、类型、虚实和主辅特征．网格生成要遵循尺寸确定和协调二项规则。

| Abstract: | CFD is a new subject produced by combining calculation mathematics,computer technique and engineering modeling.It is divided into three steps called pre-processing,solver and post-processing.The keys of pre-processing are shaping,generating of blocks and mesh.The shaping means includes static geometric model and dynamic geometric one.The characteristics of the blocks such as regions,types,ghost and shape,should be designed in iprep file.Two rules of demension determining and mesh harmony between blocks patched face to face must be followed. |
