关于icemcfd块合并问题(三角翼示例）

2016-10-07 by:CAE仿真在线来源:互联网

加号处用move vertex合并为一处,此时加号右边的两条线合并为一条。当然,两条线之间的块依然存在,而此时如果不删除这个块的话,最后生成的网格就会出现负体积(错误)。删除后重新生成网格就会解决问题。

上面的方法是错误的 (会生成如下错误)

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.

正确方法:

使用merge vertex 方法

merge vertex >collapse blocks>坍塌三角翼两遍的两个矩形block(因为如果直接删除的话在某一为零的面区域里就没有网格划分,因此会出现fatal error),之后建立恰当的映射关系即可!
