[Chehade]

Hello, i am trying to simulate the 6DOF rotation of a serrated edge wind turbine, i have drawn my turbine on solidworks and imported to ANSYS. When i use watertight geometry i get an error at eh 'generate volume mesh' (i am using tetrahedral) that says there are gaps that must be filled or refinned. However, it highlights the serration which i purposely want to remain on my blades. Is there any way to fix without having to remove the serrations? Or at least modify their geometry. Kindly find below the serration pictures.
