                                                    Hi
a boundary mesh is a quad type mesh so it cannot be created everywhere, and normally it is a operation transforming a thet/tri mesh into a local brick/quad mesh elements
If you have a closed boundary it normally works OK, sometimes in open or looped boundary conditions it does not work.
note the special selection method: first the domain(s) where you accept boundary layers, then as sub node one or several boundaries where the layers will start and propagate (into the previously selected domains

Good luck

                                                    Dear Ivar, 
Thank you so much. Now I still can not pass it. Can you help me to look at this geometry if you have some time?  I just need you help on the mesh part. And add boundary layer meshes for the cuboid. Now I attach this document. Thank you again.
