Hi Michael,

Thanks for your reply and the attachment. Good stuff.

I just think that my situation is a bit different than just a cantilevered thin beam. Modal analysis of a custom large OD pipeline system with friction and suspended masses is already an "inexact science" and using the CAESAR module + applying that equation would make it even more inexact.

I would think CAESAR has a solution or suggested methodology for this since they boast subsea analysis capabilities.

Richard or Dave, do you guys have any input on this?

I submitted a technical query to Hexagon, I am just looking for an answer ASAP since client is requesting the VIV check.

Thank you.
