fluent里面关于周期边界条件问题

gaogan1102

gambit里面划分好了网格，导入fluent里面，check时出现如下问题：

这个是模型，两边是周期边界条件，

请教下，目前fluent做网格还在用gambit吗？做出来的效果怎样（与ANSYS自己的mesh相比较）？

可能是旋转周期的角度问题，例如1/8模型的话应该是45度。我一般都是通过interface面来设置periodic边界条件，你看看你这些周期边界条件能否在fluent里重新设置吧

gambit做的，还可以吧，mesh貌似不咋地，最好学学icem

已解决了，设置了旋转轴还有周期边界条件改成了旋转的，谢谢哈！
