Hi

you have no fillet options in 3D within COMSOL (you need to use an external CAD programme then. But you can do , in COMSOL, define a workplane, draw a circle, a cut line or a rectangle then make the difference and finally fillet the sharp edge. Then you perform a revolve to get the 3D shape. Have a try

Good luck

Update on this thread: Nowadays COMSOL does include a direct 3D filleting capability in the Design Module. See www.comsol.com/design-module
