Hey guys long time no see...
So about the modeling one Russian guy made who make exact models of big ships very nice video tutorials for Rhino: https://www.youtube.com/playlist?lis...ZOSEt-rZQqbQJ4
Guys from Italia also made quite nice Naval arch modeling tuts: http://progettazionenautica.blogspot...o-lezioni.html
Holland guy I think is Phd - the best: https://www.youtube.com/watch?v=3XkdIsleAqY
This was for modeling 1 thing... But lets say we want to make variation here Rhino lacks ability so you need to delete change curves make new shape which Grasshopper improves (with sliders and a bit of programming). Ok same Holland Guy named Gerard Petersen with his very smart friends made automated grasshopper hull form deformation by sliders script https://www.youtube.com/watch?v=kgdiq4kfsaw
that can be downloaded here: http://rhinocentre.blogspot.bg/
But still new shape, make same script (first learn and understand it make control curves for hull shape deformation). Can we be better?
Lets speak a bit for hull form optimization:
Here is continuation so now there is free German software called
Caeses, which changes the game. Well very smart guy again prof. Stefan Harris. You can download and learn free version here: https://www.caeses.com/products/caeses-free/
Ok so what this software can do? that Rhino can't?
It can do parametrize Nurbs Modeling so you can
Create Variable Geometry (different boat shapes) varing by some deformation etc (from curves).
So lets see we started my thinking with lets optimize a simple boat which is made in Rhino. We put in software. Than from software to make different shapes and to go to CFD soft like Starccm there we take pressure results and use back in same soft Caeses to deform the shape (now we are discussing how) maybe by curves or FFD (box deformation like cage command in Rhino) but best is to use the pressure vectore and magnitude value for x,y,z, coordinates given by CFD soft, so to deform the shape (logic where is most pressure, deform more.( and with slider to choose how much as multiplier, so Naval Architect) can choose the amount of (trade of) optimization he wants from initial shape. Here also you can use Caeses (not free) optimizer or Mode frontier (commercial soft) or Dakota (free optimizer) if you want mathematically to recieve best trade of shape but this is still in future

Happy Winter Celebrations guys!
