SnappyHexMesh Not Snapping #6

Open btipton-ds opened 3 years ago

btipton-ds commented 3 years ago

I am having a tremendous amount of difficulty getting snappyHexMesh to snap on this and other models. I have been trying resolve this over several weeks and have spent tens or hundreds of hours on it. Originally I thought this was a user error, but today this model twice snapped correctly and produced a smooth result - but the result was not reproducible.

That indicates the problem is a non-deterministic bug. It makes the package nearly useless by itself.

Fortunately I have been using SimFlow for mesh generation which has allowed me to work - but SimFlow doesn't expose enough features to support my project and I need to get this working ASAP.

The entire case is attached with an image. It's fast (< 2 minutes.)

The image shows that only two of the three feature edges were refined correctly. If desired I can open another ticket.

I have 30 years of experience writing various forms of meshing software - if you need someone to assist I'm looking for contract work. https://www.linkedin.com/in/bob-tipton-80444315/

Oops... make that 1 of 5 edges is not refining.
