Dear Michael Fletcher,

I would like to thank for your response, kindly I request you to add these kind of local stress analysis for attached (square or rectangular) RF pad with channel member selection in vessel/tank will help in future. Also include the trunnion support attachment with pipe arrangement like can type spring analysis.

Here please advise us, for example the rectangle nozzle with RF pad is attached with cylindrical vessel intersection, then how to calculate the C11 & C22 value and for RF pad C11P & C22P value. Kindly show it as a graphical representation for easy understand local stress analysis.

Please find the attached copy of screen shot window page for your ready reference.
