For the local stress calculation in the component design of SW6-2011, there are significant differences in the results obtained for rectangular and square shapes on the housing; it is likely a software issue

I encountered this issue while calculating an ear support today. Parameters: inner diameter 4700, material Q345R, thickness 24. The local stress values entered are 800; the X-force is 462 KN, and the Y-bending moment is 212 KN·m. Choosing a square shape results in values of 308 MPa and 188 MPa, while choosing a rectangular shape does not work, with resulting values of 9290 MPa. So it must be a software issue. Please be careful when using it. Additionally, PVELite can pass both with overall calculation and component calculation.

Congratulations, you got it right. SW6 is not suitable for calculating the local stress in nozzles.
