[Helyx OS] Layers appear in mm, not in m
 

I am trying to create a good mesh with Helyx OS and am importing my geometry in mm.
When I add Layers on my outside faces:
(Number of Layers: 3
Layer Stretching: 1.25
Final Layer Thickness: 0.4)
no layers appear, but when I import the geometry in m with the same layers settings (and scale the base mesh and the material point accordingly) the layers appear.
I have checked the relativeSizes in the SnappyHexMeshDict and it is true.
What can I do to have the layers appear in mm?
Thank you!

After searching all over the Internet I found the response to my problem here: https://www.simscale.com/forum/t/how...ll-models/9187
I had to change the min. vol of faces from 1E-13 to 1E-21 because I am dealing with really small geoemtries
