snappyHexMesh Warnings "displacement" and did not visit some faces" erros

Hello people,

I'm trying to use SHM to mesh a cylinder with 3 sections. I want to use each section to create 3 cellzones that later I will use to apply porosity in one of them.
I have 4 STLs. One for each section and one for the whole cylinder.

When I run I get Warnings about "did not visit some faces", "displacement" and about illegal faces.

At the end, it just meshes the background.
Somebody knows what is wrong?

Thank you in advance!

Hi!
I'm having the same problem as yours. Do you find a solution?

Best regards

I just found this thread and have the same Warning.
Did you guys find out why it shows up? Or does anyone else know how to avoid this warning?

I think that it has something to do with the coordinate system of OpenFOAM and the used CAD system. But that's just a guess right now, have to try around a bit and see if it affects the meshing.
