SubscriberHi All,
I have been trying to simulate a fluid simulation with a solid geometry in the middle of the fluid domain. The solid geometry is a bit complex and has a V type cylindrical shapes. I tried improving the mesh by giving a body sizing option for the solid part.

Ansys EmployeeThe min orthogonal quality should be above 0.1 to proceed to solver. If it is less than 0.1 then please improve the mesh.
First check the locations of the bad elements. Please see following video for the same.

Once you have locations, please check if you can improve mesh using different mesh sizing. Please see following video.

If this does not help, you may need to check if you can use pinch control or virtual topology.

If this does not help, please go to geometry and modify or simplify geometry at those locations in SpaceClaim.
