algorithmic modeling for Rhino



Naval Efficiency and Marine Optimization
Nemo is a Grasshopper plugin for Ship Design



Nemo provides multiple tools to generate linesplan, compute hydrostatics, perform resistance prediction, extract structural data, produce 2d drawings, and exchange data with other external software. Nemo also includes free tools to create parametric shapes, such as Naca profiles, hydrofoils, keels, rudders, blade propellers, and sail plans.

Born in 2018 as an academic research project at ENSTA Bretagne, Nemo grew up since, immersed in professional naval architecture practice with L2Onaval.

From 2021, Nemo is now available for purchase with commercial or educational licenses. Following license levels are provided to fit every needs depending of user activity :

  • Free (Designer)
  • Level 1 (Section + Hydrostatics + Visualization)
  • Level 1 + 2 (Section + Hydrostatics + Visualization + Resistance + Structure)

We can also help you make best use of our software, provide project guidance, establish specific workflow and create custom tools.

Never fear, my computer literate girlfriend has worked it out and it's there in the toolbar! success! Now I must merely learn to use it...

I'm struggling to get your plugin to install. I unpacked to  C:\Program Files\Rhino 6\Plug-ins\Grasshopper\Components and that didn't work. I don't seem to have your folder address on my machine.

Is it possible that I need to install kangaroo and another plugin first?
