Because I am using the sliding mesh approach, I have defined 3 cell zones:<\/p>\n<p>-2 cylinders from which the screws have been subtracted and which will be rotating (red and purlple-ish)<\/p>\n<p>-1 static zone, which is the container of the screws (light-blue)<\/p>\n<p>I have defined boundary layers along the walls of the screws and the walls of the container. On top of that, I have defined a boundary layer on the sliding mesh interface. When I generate the poly-hexcore mesh, the boundary layer on the sliding mesh is weirdly stitched together with the boundary layer on the wall of the container (see picture below). Is there a way to enforce a better alignment of the 2 boundary layers? The most obvious solution, in my opinion, would be to not create any polyhedrals, but have prisms throughout this region. Is there a way to tell the mesher to do so?
