If the flow domain is split into several parts and each part is meshed independently,
you need to ensure that the mesh is consistent/matching at the interfaces.
After meshing the first volume (on the left), the shell elements on the interface between
the left and right volume have to be selected as W/o BL (fixed) for meshing the right volume
to ensure the matching interface. This works for pentas, hexas and tetras in the BL. Figure 1.
