problem to substract model from enclosure

sarafali · May 18, 2015, 16:01

hi everyone,

I need urgent help.

I am trying to substract a wind turbine blade from a cylinder enclosure by using boolean feature and it keep showing error message. Can someone guide me to solve this issue.please..Below I attach my drawing for your review.Tq

If you need urgent support then pay for TECS and contact ANSYS support. That's what you pay them for. Nobody gets paid on the forum so we answer in our own good time.

The non-manifold body error means you are trying to generate a body which is not a solid volume. Is the rotor you are using a solid body or are the blades just surfaces? If the blades are just surfaces that would generate a non-manifold body error.

You need to either make the rotor a full 3D body with a volume, or use the thin surface options to create 2D blade surfaces.

thanks for your reply. The blades are solid body which I've imported from solidworks. I dont really know how to make it become solid volume body. Can you help me? sorry, I'm still new to this software and I did not really understand the features.

Try the geometry and meshing forum - but there is not much more I can say beyond what has been said. You probably have a surface body somewhere - you need to find it. It might be a geometry import problem, or it might be the actual geometry.
