摘要

在铸造CAE后处理中

需要对铸件孤立气相域进行填充显示

但是随着铸件复杂程度的不断增加

扫描线种子填充算法已无法适应铸造CAE后处理模块显示海量数据的需求。通过改进原算法

修改栈结构

使得扫描过的线段和填充过的单元不再分别进行扫描和填充

减少了数据计算量

并行计算大大缩短了填充和显示时间。通过多个实例验证了改进算法

提高了复杂铸件孤立液相区域的显示速度

且填充区域越大

节省时间越多。

Abstract

In the post-processing of cast CAE

it is necessary to fill the isolated gas phase of the casting

however as the complexity of the casting increases

the scanning line seed filling algorithm cann’t adapt to the demand of the massive data generated by the casting CAE post-processing module.By modifying the original algorithm

the stack structure was modified

so that the scanned line segments and the filled cells didn’t need scanned and filled

respectively

which reduced the amount of calculation data

and the parallel calculation greatly saved the filling and display time.The results of several examples show that the improved algorithm can improve the display speed of isolated areas of complex castings

and with the filling area increase

the more time is saved.
