Dear community,

I am trying to mesh a journal bearing which more or less consists of two pipe surfaces with different diameters (61.32mm and 61.205mm) as you see, the resulting gap is only 0.0575mm high. The geometry was developed in DM.

From the many problems I have already encountered, there are two, which I have no idea where they come from and much less how to solve them.

1. When generating a PreMesh, at some points periodic around the geometry, Icem melds the surfaces. That of course divides the gap and leads to an unusable Mesh.

2. The Mesh has a large amount of inverted volumes and smoothing only leads to more inverted volumes.

I used an O-Grid.

If you need more details, please ask me for them.

I would be very glad if somebody told where the problems result from and how to solve them.
Thank you,
Pac
