Nurbs curve interpolation
WebIn this study, a novel NURBS-based degenerated stiffener element is proposed. Based on the 6 degree of freedom (DOF) degenerated beam element, the proposed stiffener element solves the issue of direct coupling between the beam element and 5 DOF degenerated shell element. Skin and stiffener are characterized by NURBS surface and curve, respectively. Web15 aug. 2016 · To reduce the ship wave-making resistance, the lines of the bulbous bow of a hull are optimized by an automatic optimization platform at the ship design stage. Parametric modeling was applied to the hull by using non-uniform rational basis spline (NURBS). The Rankine-source panel method was used to calculate the wave-making resistance. A …
