You don't - CAESAR II models "pipes" using the "3D Beam" element. This element is not sufficient to model flexible hose. In addition, the stiffness of the hose is so much less than that of the pipe, the pipe sees the transition point as a free end.
pipesnpumps,
I just wanted to "raise" a question as I had not heard of a "Breaded Metal hose" and thought it may be similar to a "croissant" but C2it corrected my mistake and put me right with it being a Flanged baguette. It's always worth asking at "yeast" you get the right answer from somewhere!!
