powerHull GH

powerHull-GH is a collection of Grasshopper components to perform resistance and power requrements prediction within a Grasshopper workflow. Attaching powerHull-GH to a parametric model or a stanadard Rhino3D NURBS model, one can preview resistance, power requirements as well as hull motions in real-time.

Features

  • Metric or Imperial units.
  • Prismatic, semi-empirical methods: Savitsky, Savitsky win “M-Factor” (corrected for lower than planing speeds or planing hulls at “hump” region.
  • Regression methods: Series 62, Series 65
  • Appendage resistance including rudders, shafts, struts and trim tabs.
  • Air drag.
  • Results include: bare hull resistance, appendage resistance, air drag, margin resistance, total resistance, effective power, shaft power, total power, running trim angle, critical trim angle (limit for dynamic instabilities), special comments.
  • Attach the parameters of your Grasshopper parametric model or “link” it directly to your Rhino3D model
  • Combine powerHull-GH with Tunny or a similar Grasshopper optimization plugin to perform design parameters optimization (ex. optimize deadrise angle or chine beam for resistance)
