最近是用topoSet和refineMesh局部加密。如果加密区域在单个block内可以正常运行，但加密区域在两个内就会出错。
我的疑问：topoSet和refineMesh命令：topoSet 和 refineMesh 选定的区域不能包含两个block对么？ 如果想对横跨两个block的区域加密，怎么实现呢？ 是在各自的block内分别加密么？
topoSet和refineMesh 运行都是正确的
两个block信息如下
vertices
(
( 0.0 0.0 -10.0)
( 100.0 0.0 -10.0)
( 100.0 5 -10.0)
( 0.0 5 -10.0)
( 0.0 0.0 5.0)
( 100.0 0.0 5.0)
( 100.0 5 5.0)
( 0.0 5 5.0)
( 0.0 0.0 100.0)
( 100.0 0.0 100.0)
( 100.0 5 100.0)
( 0.0 5 100.0)
);
blocks
(
hex (0 1 2 3 4 5 6 7) (200 10 30) simpleGrading (1 1 0.2)
hex ( 4 5 6 7 8 9 10 11) (200 10 200) simpleGrading (1 1 5)
);
topoSet命令如下
actions
(
{
name c0;
type cellSet;
action new;
source boxToCell;
box (0 0 -3) (100 5 10);
}
);
refineMesh的命令
refineMesh -overwrite的命令运行也正常
checkMesh -allTopology -allGeometry结果如下
