關于icemcfd塊合并問題(三角翼示例）

2016-10-07 by:CAE仿真在線來源:互聯(lián)網(wǎng)

加號處用move vertex合并為一處,此時加號右邊的兩條線合并為一條。當然,兩條線之間的塊依然存在,而此時如果不刪除這個塊的話,最后生成的網(wǎng)格就會出現(xiàn)負體積(錯誤)。刪除后重新生成網(wǎng)格就會解決問題。

上面的方法是錯誤的 (會生成如下錯誤)

Error:

FLUENT received fatal signal (ACCESS_VIOLATION)

1. Note exact events leading to error.

2. Save case/data under new name.

3. Exit program and restart to continue.

4. Report error to your distributor.

正確方法:

使用merge vertex 方法

merge vertex >collapse blocks>坍塌三角翼兩遍的兩個矩形block(因為如果直接刪除的話在某一為零的面區(qū)域里就沒有網(wǎng)格劃分,因此會出現(xiàn)fatal error),之后建立恰當?shù)挠成潢P系即可!
