Thanks Richard Ay,
I already sent my file to technical support of coade.
In relation to my post, I have additional query regarding the limitations stated in WRC 297. In my case, Dn/Tn (=18.098) < 20 which is not valid to thin-shell theory. It was also stated in the bulletin that the exact limit of application depends on the Dn/Tn ratio.
Where;
Dn= Outside diameter of the vessel.
Tn= Wall thickness of the vessel.
The following are my questions:
1. Does it mean WRC 297 it not applicable in the case I'ved analyzed?
2. How about the rest of those limitaions if not meet, still WRC 297 is not applicable?
3. Caesar II Provide only a warning not an error. Do I need to continue my analysis?
