<p>Hi Michael</p>
<p>OK, sounds good. I'm teaching at Plastics|SA the whole of this week but should be able to get some good study time in next week, then set up a simulation.</p>
<p>Was also thinking of modeling a (traditional) bow allowing for various limb forms, thicknesses, chords or cross sectional shapes. That's interesting because a bow is simultaneously a spring and a 'gearbox' - the load vector is dynamic.</p>

<p>Hello Ian,</p>
<p>A spring is a good place to start. It is relatively easy to model while simultaneously being non-trivial. We'll have to limit it to compression springs with a gap between the coils. In the case of your torsion spring with coils touching, the simulation grid will cross the space between coils and the results will be incorrect.</p>

<p>Hi Michael</p>
<p>Fantastic, thanks! I'm very excited about the prospect of allowing SnS to self optimise geometry. It contributes directly to the growing demand for 'lightweighting' and recycled materials with impaired mechanical properties.</p>

<p>Let me get my head around your examples and I'll look for a 'real world' problem to solve. What if we started with something simple like a spring? I had such a problem, solved by plugging test values into Excel. It solved the problem; within a year it became a top selling product (PDF attached).</p>
<p>SnS migrated to Grasshopper would be mind blowing. For someone like me familiar with a bit of programming but not actively coding, porting your skills to a graphical interface like Grasshopper gives us a big jump start.</p>
<p>I really wouldn't have felt comfortable designing this chair back, for instance, without SnS.</p>

<p> <a href="http://www.intact-solutions.com/snsscript_documents/index.htm">http://www.intact-solutions.com/snsscript_documents/index.htm</a></p>
<p>These examples discuss using SnSScript to compute simulation properties rather than creating or changing geometry using RhinoScript.</p>
<p>To find examples for editing geometry within RhinoScript, maybe check at rhinoscript.org: <a href="http://www.rhinoscript.org/">http://www.rhinoscript.org/</a>. I've been interested in creating an example where SnSScript is part of an automated geometry modification loop, but inventing compelling and understandable examples takes time. There always seems to be something else that requires attention.</p>
<p>The current architecture of SnS is not amenable to coupling with Grasshopper. Grasshopper and PythonScript are based on Microsoft's .NET programming technology, the direction in which plan to eventually migrate a future version of SnS.</p>
<p>Thanks,</p>

<p>Hi Michael</p>
<p></p>
<p>It has undergone a redesign with honeycomb in the center - I have found that tends to dissipate loads well. I've been looking for inspiration in dragonfly wings as they seem to use loads carefully to subtly shape the wing. Will be modelling and SnS'ing that soon.</p>

Ian,<br />
Very cool geometry, and outputting to 3d pdf to boot!<br />
The arching of your reinforcing ribs has a close resemblance to the Michell truss-like structures that are seen so often in nature and as output from topology optimization algorithms.<br />
Now you just have to program the design into RhinoScript, put it into a loop with SnSScript, and optimize the layout of the ribs. ;-)<br />
Thanks for posting!<br />
