大型结构多阶模态快速动画显示方法

Fast Animation Display of Large Structure with Multistep Modes

采用MS-FORTRAN5.0和宏汇编语言接口的方法将屏幕上所显示的某一阶模态图形通过访问VRAM,存贮在指定的磁盘文件中,然后根据需要,将文件内容读入VRAM中,以实现模态的快速动画显示。该方法避免了一般方法因多阶模态图形需开降辟多块内存区域来实现动画显示,从而克服了内存不够的缺点。作为移植到微机上的SAP5和ADINA有限元分析程序的一个功能模块,用该方法编制的程序模块可对大型结构的多阶模态进行快速动画显示。

The method that the MASM assembler is interlaced to the MS-FORTRAM 5. 0 is used to store some step structural mode drawings in the designated disk file through their visiting VRAM,which are then restored in it when needed in order to realize the quick animation display of the mode. This method solves the problem of insufficient memories in storing multistep structural mode drowings with the ordinary method. As a functional modular of finite element analysis programs SAPS and ADINA transplanted to a microcomputer,the modular programed with the above method can quickly display the animation of large structure with multistep modes.
