關(guān)于icem wbrcfd wbr塊合并問(wèn)題(三角翼示例)

加號(hào)處用move vertex合并為一處,此時(shí)加號(hào)右邊的兩條線合并為一條。當(dāng)然,兩條線之間的塊依然存在,而此時(shí)如果不刪除這個(gè)塊的話,最后生成的網(wǎng)格就會(huì)出現(xiàn)負(fù)體積(錯(cuò)誤)。刪除后重新生成網(wǎng)格就會(huì)解決問(wèn)題。

上面的方法是錯(cuò)誤的 (會(huì)生成如下錯(cuò)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(gè)矩形block(因?yàn)槿绻苯觿h除的話在某一為零的面區(qū)域里就沒(méi)有網(wǎng)格劃分,因此會(huì)出現(xiàn)fatal error),之后建立恰當(dāng)?shù)挠成潢P(guān)系即可!
