Navigation:  Hydrostatics & Stability > Design Hydrostatics

Orca3D can compute hydrostatics and stability in various combinations of waterplanes/displacement and center of gravity/heel/trim, with a range of heel angles. However, while you are fairing a hull, you are usually just interested in the hydrostatics at the "design waterline," or at a particular displacement/center of gravity, and you don't want to have to open a dialog and enter values each time you repeat the calculation.

To simplify this process, Orca3D has a special Hydrostatics and Stability condition called the "Design" condition. The intent is to define the Design condition once, and then as you create and modify the hull, you can compute hydrostatics and stability at that condition with a single button click. This saves having to go through the dialog to define the condition each time you wish to compute the hydrostatics. Also, the Design Condition can be used as the condition to evaluate in Planing or Displacement resistance calculations.
