Hi,

I have transferred data from a hydrodynamic diffraction system to an upstream static structural system using the hydrodynamic pressure add-on. I am using the static structural system to determine loads within a floating structure (axial loads and bending moments through beams). I would like to represent these loads as RAOs, to show the loading through each beam at each wave frequency and each wave direction. I am wondering whether it is possible to generate these RAOs within Ansys, or will I have to export the data and create these plots myself?

You could directly have the bending/shear force RAOs from Aqwa-Line (Hydrodynamic Diffraction analysis) by defining the mass distribution along an axis.

I see, okay thank you.

Is there a native way within Ansys to generate beam axial load RAOs?

[Shuangxing Du]

Yes, it is in Hydrodynamic Diffraction analysis. Once the point masses along X or Y axis are defined, or the mass distribution along X or Y axis is import into Aqwa editor in Workbench, the bending/shear force calculation can be selected and the results could be output

Great, thank you very much!

You are welcome.
