摘要： VFAS 软件系统是以原角系数程序VF01、VF02为基础,采用了新的数学方法,改变表面之间的角系数计算为结点之间的角系数计算,解决了辐射干扰结点的自动判断,将人工划分与组合的大量繁杂工作全部由软件系统完成,大大减轻了工程设计人员的工作量,且使计算精度得到根本改善。

Abstract: Based on VF01 and VF02,VFAS system has made a great progress in reducing the user's man-hour and improving the accuracy of the calculation results.The calculation of viewfactor among different surfa- ces now may be changed into that among any different nodes,and the shadowing between nodes can be decided automatically by the system.
