How to create inflation layers around sharp corners in Ansys workbench meshing? ( attach image)

I already try to use slice. I cut it in two parts. One is nozzle and one is box. In meshing I make connection between them by matching face of nozzle at outlet and face of box 

Still i am not able to generate inflation layers around sharp corners.

Looking for some suggestions.

Thank you for your time.

Slice the grey box horizontally at the top and bottom of the inlet to the green nozzle. Use Shared Topology to keep the three parts of the grey box conneted. Now you can use inflation on the two new edges in the grey box. You can also apply inflation to the vertical edges of the grey box to get the inflation to go around the corner.

I wonder if the corner is dead sharp, or if there is in fact a small radius on the corner.

Corner is dead sharp. I am studying the characteristics and behavior of flow which is passing through swirl nozzle. 

Thank you for your answer. I will try

Did not work.  It says assembly meshing inflation meshing has ignored inflation controls on faces which have been defeture out or are omitted from the initial assembly mesh.

Now I see it is a cylindrical body. It looked like a 2D model in your original post.

The procedure is the same idea.  Take the circular edge of the nozzle, and extrude that as a zero thickness surface through the box as a Cutting surface to slice the box into two pieces, a cylinder and a box with a hole in it. Now the inflation can be continuous inside the cylindrical wall, both in the nozzle and in the box.

is there any reason you sliced the geometry after nozzle in vertical direction. 

in simple way, i would merge/unite all bodies. this will give me continuous inflation. then i will use body of influence to get refined mesh as required.
