Thank you for your response, Dave.

If that's the case, I will have to defer to the subsea company for the VIV assessment. Too bad because I was excited to try to do this.

Interesting what you mention about those two points. I will make it a point to use Eh or E for your 1) point.

But can you please expound a bit more on your 2) point? Does this mean that the modal analysis module of CAESAR is not reliable for systems that have any degree of stress within them, be it from temperature or sustained loads? This seems like a very limiting requirement. It makes me a bit alarmed about modal analyses I've ran for loaded systems like hot reciprocating compressor lines which as you know are rigidly clamped down.
