Subdyn-Hydrodyn coupling for non beam elements

[Maurizio.Collu]

Sorry, below the complete link.

Withouth infringing any IP, the system is basically the same (has been beefed up a bit) of the previous post. Also an image below.

Long story short, the reaction point at bed level of the main column is a universal joint, so without the 9 tension cables the whole platform will just rotate (rigidly) around that point.

Modelling in SubDyn a tendon pinned at the top and connected to a universal joint at the bottom (piled anchor)

Thanks a lot, @Jason.Jonkman. You actually foresaw one question I had: how the SubDyn module understand that is a fixed or a floating platform (and I suppose this is what is declared at the beginning of the simulation once launched). Based on what you mentioned, if there is a reaction joint (at the seabed), then SubDyn adopts the “fixed” approach (independently of the GuyanLoadCorrection being on or off), while if there is no reaction joint, then it considers the platform floating, correct? I…
