Mode Shape Stresses

Hello

I am currently looking into performing a VIV (Vortex induced Vibration) fatigue analysis on a deepwater rigid spoolpiece. Is there any way we can output the stress associated with the modeshapes that have been calculated in the modal analysis in AutoPIPE? If i was able to do this i could output the modal displacements and the associated stress into an external program. 

Can you help or do you know of some sort of fudge to get the stresses out i.e. harmonic analyses etc??

Thanks in advance
