This is using cfMesh - I get mesh quality issues when using gmsh, probably due to a small gap or misalignment somewhere (which cfMesh and snappyHexMesh tend to be more robust to by their design).
Don't forget to look at the checkMesh output - I suspect you will find it is poor in the gmsh case. Otherwise, uploading the exact case that is giving you an issue should make it possible for someone to assist.Crossleyuk wrote: ↑Wed May 25, 2022 7:58 pm Hi TH,
I tried your case and sure it meshed in cfMesh and gmsh but could not get it to run at all. So I've continued with my rebuild using gmsh and note that the case fails every time the Residuals climb higher. Here is what I'm getting every time.

Cheers and thanks for the contact again.

You beat me to it Oliver and thanks yet again to you and ALL. I had just completely rebuilt my model with little success so changed to "Part" rather than Part Design and finally a Fusion. That again failed with elevated Pressure residuals so your's is now running with me fingers crossed, after finishing this post. Will let you know the result and happy to offer more details of my additional tries if you think it may be of assistance
