Hi, I am trying to mesh a sharp edge orifice that has a radius between the 2 cylinders.

Here is a zoom of the sharp edge. I made the radius by moving some vertices to create a radius, but I am concerned about the non-smooth transition between the angles of my cells.

Do you guys have any ideas how could I have a better mesh around the radius. I want to keep the rest of my mesh as quad cells.

Thank you

Try to understand the following prostar-code. It tells you how to create a wall parallel sublayer on an existing mesh.

Code:
vc3d 0 1 20 0 1 20 0 1 20

ctab 10 shell 4
ctab 11 shell 5

Hi, thanks for answering, but I'm not sure you understand what I need.

I need to make a sharp edge that consists 2 cylinders joined together and I need to make a radius so there is no more sharp edge. I just want to have a smooth mesh where my radius is

A wall layer is usefull for sharp edges and also for a radius. You can smooth the mesh later using the "vell" and "vsmoo" comands.
