Hi

I'm performing a VIV fatigue analyses of proposed 3D spools design based on DNV-RP-F105. The proposed spool contain 2 large spans. I've calculated the natural frequency, but now I need to calculate the unit diameter stress amplitude (this is defined in F105 as the stress due to unit outer diameter mode shape deflection). How can I calculate this in ABAQUS?
