How to design Bracing(Morison Element) in Rhino!

[karmoker18]

Hello, I'm doing my BSc thesis in hydrodynamic diffraction of a cylinder shape objects. I'm stuck in a problem on designing bracing elements (Morison Element, identical to spider web in bottom).Can you please help me on how I can model Morison Element in rhino and join that with the main cylinder body?

Regarding issues with other commercial software like Rhino, I suggest to find the user manual or directly ask the customer service department of that company.

Dear Prof. Liu, Thank you very much for your reply. For a novice user like myself, your HAMS software appears to be very intuitive and practical. Nevertheless, I have the following questions:

I am attempting to calculate the hydrodynamic added mass coefficients for a hybrid structure (consisting of pressure panels and Morison elements) of a semisubmersible type floating offshore wind turbine (FOWT) platform. According to my knowledge, HAMS converts slender structures into diffraction elements (pressure panels). Please inform me if my understanding is incorrect.

Is it possible for HAMS to convert slender elements (such as the bracings of a semi-submersible) to Morison elements?

Is there a smart/user-friendly way to convert a Rhino model (having both large diameter and small diameter pipes) to the Wamit (*.gdf) format? If a Rhino model is 'save as' gdf model, it does not produce results comparable to 'marin semi low.gdf'. Is there any advise from you?

are you take care of the Normal direction when you construct the semi-submersible in rhino?
