I am designing a dynamic geometry in grasshopper as kinetic facade. Then, I am aiming to use DIVA for grasshopper to analysis its annual daylight performance.  However, I cannot define my dynamic geometry as shading's under materials in DIVA for grasshopper.

Is it possible to define the dynamic geometry as kinetic shading with material layers in Diva for grasshopper or no?

Hi Alireza,

I apologize that no one has responded to your question up until now.

DIVA-Grasshopper only allows one shading state (on or off) per window, not a multi-state system, so it may not be pertinent for your study. This tutorial may help you achieve your goals using the Rhino toolbar.

Hi Alstan

I build a geometry in rhino and want to rotate the shades in grasshopper but the original shades did not move and only the highlighted ones generated by grasshopper is rotating, which dose not allow me to analyse the daylight performance under different angled shades. Once I bake the rotated geometry by GH, it does not movable again. Any method to solve this?

Hi Chan,

I think you'll want to review the Grasshopper 3D user guide: http://www.grasshopper3d.com/page/tutorials-1

And the DIVA-for-Grasshopper tutorial videos: http://solemma.net/TrainingGH.html

Hi Alstan,

I still cannot figure it out.

As I am using galapagos to run the optimisation, there is no actual physical shade there in rhino for each angle it tests, so the result from diva dose not change alongside the rotation of the shades.

I am new to grasshopper and I really want to understand the mechanism behind the galapagos+diva optimisation.

I will appreciate your help with this.

Hi Chan,

Its hard to give good advice -- I think you need to become more familiar with Grasshopper and Rhino workflows first. Try working through all of our GH tutorials by Jeff G. and the Grasshopper users guide.

Essentially, the idea is that your entire simulation is setup in Grasshopper parametrically. That way the simulation, geometry, and results processing are all controlled within one environment. Moving anything over to Rhino will result in a static geometry.

One option is to use Galapagos to generate 'optimal' parameters, and then bake those results to Rhino for deeper analysis.

Best,

Alstan
