ansys flunt网格划分时出现这个错误，怎么解决，求大佬帮助一下，可以吗？

The mesh file exporter does not support overlapping geometry in named selections.  Please resolve the issue and try again.  You can use the option “Show Geometry in Overlapping Named Selections” (when you right click on the Mesh branch of the tree) to help diagnose the problem.
