Hello,everyone

I'm trying to mesh a volute with tetra mesh.
The mesh check shows there are several elements with problem"added faces" and "Delaunary vioaltion". When I load the mesh into cfx, the cells with "added faces" are lost.
How can I fix this problem?
Thank you for your help and time.

Have you done a build topology first ?

Yes! I built the topology. But it is still there.
I made screenshots. The elements are belong to different parts.

it looks like you have two surfaces sharing one edge, if so have you activated thin cut ??
