Reply To: Non-conformal Mesh: Boundarie is automaticly set to wall instead of internal

[Ivosp]

So the settings I used for describing the geometry are (the ones I changed is written in bold)

• Geometry Type -> The geometry consists of both fluid and solid regions and/or voids
• Will you cap openings and extract fluid regions? -> No
• Change all fluid-fluid boundary types from 'wall' to 'internal'? -> Yes
• Do you want to apply Share Topology? --> No
• Enable Multizone Meshing? -> No

The boundary types I used for the touching spherical surfaces are internal. 

I didn't change the rest of the settings.
