3d transition patterns
 

Is it possiable to specify a boundary layer mesh transition pattern apart from 1:1 on a face of an internal 3d block. When I set the face boundary layer mesh of the face on the block the attachent changes from face to edge when the trasition pattern is changed from 1:1 to any others (4:2, 3:1, 5:1). When I mesh with this boundary layer mesh inside the block I recieve an error with hex submap, hex tri-primative and tet/hybrid. Any help?
