基于VB和FORTRAN混合编程的时程曲线绘制

Time History Curve Drawing Based on Mixed Programming of VB and FORTRAN

大体积混凝土坝施工仿真常常历时数年,需要知道任意给定点的物理量值在某一时间段内的变化情况。为此,采用VB和Fortran混合编程的方法,以动态链接库DLL文件作接口,结合VB时程曲线绘制方法,研制了混凝土坝时程曲线显示模块,作为后处理软件的一部分。该模块可以高效显示混凝土坝任意给定点的物理量值在某一时间段内的变化情况。

The construction simulation of large-volume concrete dams often lasts for several years,and it is necessary to know the changes of the physical quantity of any given point within a certain period of time.For this,using VB and FORTRAN mixed programming method,using dynamic link library DLL file as interface,combined with VB time history curve drawing method,concrete dam time-history curve display module is developed,as part of post-processing software.The module can efficiently display the change of the physical quantity of any given point of the concrete dam within a certain period of time.
