CFX-5 mesh generator provides: Automatic mesh generation Unstructured triangular surface mesh generation Tetrahedral/prismatic volume mesh generation There are three modes of volume meshing in CFX-5

CEL is an interpreted, declarative language which enables users to enhance simulations without recourse to external fortran routines. It uses mathematical expressions for physical quantities as opposed to using fixed values. Access to CFX-5 internal variables (including solution variables)

Tools / Lists : - is a temporary selection of entities - can be used as immediate input to a select databox - can be given more permanence by storing it as a group

利用大型商业软件CFX建立了高温氮化硅反应炉内温度场的数学模型,采用拟流体模型数值模拟炉内的层流流动,分析了氮气体积流量、各向异性散射和辐射特性等因素对温度场和产物质量浓度的影响.计算结果表明,为确保反应充分完全,预热段温度控制显得非常重要,而氮气体积流量起着决定性的作用;各向异性散射对径向温度、产物质量浓度有一定的影响;散射率对温度场影响很小;计算值与实验值相比较,误差在10%之内

The initial tolerance is important for geometry construction and grid construction. The preferred method to set the tolerance is to work from the Preferences pull down menu and select Global
