MOLDFLOW模流分析结果解释

MOLDFLOW模流分析结果解释

解释结果的一个垂要部分是理解结果的定义，并知道怎样使用结果。下面将列出常用结果的定义尺怎样使用它们的建议，越常用的结果将粒尢介绍。

屏幕输出文件(screen output)和结果概要(results summary)

屏拿输出文件和结果概要都包含了一些分析的关键结果的总结性信息。屏幕输出文件还包含如图169所示的附加输出，表明分析正在迸行，同时还提供重要信息。从它可以看出分析使用的压力和锁模力的大小、流率的大小和使用的控制类型。

Filling phase: Status: V = Velocity control

P = Pressure control

V/P= Velocity/pressure switch-over
