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,最后生成的網格就會出現負體積(錯誤)。刪除后重新生成網格就會解決問題。
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域里就沒有網格劃分,因此會出現fatal
error),之后建立恰當的映射關系即可!
