algorithmic modeling for Rhino



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



Nemo is divided in two major parts :

  • Nemo Analysis, for automatic analysis of ship geometry (licensed)
  • Nemo Designer, which includes several design tools (free)

Nemo Analysis can perform hydrostatics computation, silhouette extraction, meshing generation and resistance prediction right inside Rhino.
Sectioning hull into stations - buttocks - waterlines, generating an offset table, or creating cross-sections curves are also embed features.
Interoperability is allowed with external software like NavCad (HydroComp), Mars 2000 (Bureau Veritas) or Excel (Microsoft).

Nemo Designer includes specific tools to create NACA sections and appendages such as hydrofoils, keels (with or without bulb), or even blade propellers.

Nemo full version is provided for free (no license file needed) at least until : 2020-12-31



PC Windows 10 :

  • McNeel Rhinoceros 6 | Developed and tested on Rhino 6 SR18.

Not tested on Rhino 5, WIP and MAC versions, but could (partially) work.

Feedback :
As Nemo is continuously growing up, any feedback and improvements are highly appreciated.

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?
