Full load. Areas, lengths and volumes come from the model, the laminates and all other masses from params.js.
The sandwich structure as a shell of finite elements, in the test of the sheet: the boat at full load stands on three hull corners at the first and the last bulkhead, the fourth (port stern) is free. This twists it like a diagonal wave.
Stress in the skins: largest principal stress on their outer faces, away from the supports; "99 %" is the value that 99 % of the area of a zone stays below and what "used" compares with the design value; "peak" is the largest single value. Peaks sit at the sharp corners of openings and rise with a finer mesh; red: above the design value. The struts are left out (conservative); no buckling check.
