Hello All,

While attempting to model a flexible nozzle using WRC 297 (following the guidelines set forth in the CAESAR II Application Guide "Flexible Nozzle - WRC Bulletin 297") I noticed that after running the Error Checker the WRC 297 Nozzle Calculations Caesar II reported an Axial Translational Stiffness (lb/in.) of approximately 10E12 which is the default rigid stiffness value. I'm trying to understand why the software is defaulting to this value?
Furthermore, I noticed that Caesar II software provided a note stating that "The following combinations produce rigid axial junctions: j>1 .6 &=10 / j>2.5 &=20 / j>4 .0 &=50/ j >6 . 2 &=>100". Yet, the calculated j=2.562 and &=3.878. If anyone can shed some light on this issue it would be greatly appreciated.

Thank you.
