[Moving Mesh] Changing unit (dm>mm) leads to inverted mesh

Hello,
I have a model which works well when I use a macroscale (like meters), but, when I change the scale (millimeters), the calculation leads to inverted meshes.
As I changed everything in the same proportion, I have expected that only the physics would change (here Navier-Stokes > Stokes flow), but apparently some geometry/meshes are also changed.
Could you give me some hints on what to look for, because I really don't understand this behaviour.
Thank you in advance

Hi
check carefully the new sizes of your model, depending if you hit the scale values check box, COMSOL's logic was not the same as mine, so I had too some surprises in the beginning. ;)

Good luck
