Hi, regarding your questions:

  1. you can define the node as a connection point of the structure (right-click on the structure/Part under the Geometry branch in the Outline tree > Add > Connection Point), and then in the Details panel of the Structure Motion result, change Reference Point to the Connection Point you define.
  2. To define the wind/current coefficient, right-click on the structure/Part under the Geometry branch in the Outline tree > Add > Wind/Current Force Coefficients. You can find wind and current forces are calculated in Aqwa Theory Manual Section 2.2, 2.3, 7.1.
  3. Aqwa provides gravity force, acceleration, joint reaction force, and fender forces results, which can help you calculate g force depending on how you model.

Hope this helps.
