@李东岳 网格是用fluentMeshing画的，严格按照周期性边界设置的，导入OpenFOAM之后，当matchTolerance很小的时候，使用createPatch设置周期性边界的时候会报错，
以下是 createPatch 代码
patches
(
{
name cyclic1;
patchInfo
{
type cyclic;
neighbourPatch cyclic2;
transform rotational;
rotationAxis (0 0 1);
rotationCentre (0 0 0);
matchTolerance 1e10;
}
constructFrom patches;
patches (cyclic_1);
set f0;
}
{
name cyclic2;
patchInfo
{
type cyclic;
neighbourPatch cyclic1;
transform rotational;
rotationAxis (0 0 1);
rotationCentre (0 0 0);
matchTolerance 1e10;
}
constructFrom patches;
patches (cyclic_2);
set f0;
}
);
以下是报错信息
