结构流程图 meaning in English

structure flowcharts

With the flowchart the program can be divided into six parts and it includes initial flow field , computation of molecular motion , boundary treatment , re - sort of molecular , sample and computation of molecular collision . several cases have been simulated to certify the correctness of the program . dsmc method is improved using method of characteristics to modify the boundary condition and gets the goal as expected
首先,编程实现了基本dsmc方法对二维流动的计算,给出了所用算法的原理、相关模型,并结合程序结构流程图,分别介绍了初始化流场、计算分子的运动、边界的处理、分子的排序、抽样计算分子的碰撞、流场参数采样统计各个功能模块在fsmm2d中的实现,并对该程序进行了算例校验。
