As part of an investigation into gridshells I posted in the Grasshopper forum to try and find a solution to a definition using the bend force component through the Kangaroo plug-in for Grasshopper.
My intention was to deform a grid into lathes using a bend force whilst maintaining the overall length of each lathe (or curve) as a representation of how gridshell are constructed on site, where they are raised or lowered into position from an originally flat grid, and deform or bend due to their own self weight.
Daniel Piker the creator of Kangaroo replied with a very useful script component that allows the user to easily find the correct inputs for a divided curve that is plugged into the bend component.
He also very kindly finished the definition for me.
The files including the C# script component can be found in the forum post here if you would also like to investigate the bend force.

LMN Architect has just published a review of the DIVA plugin for Grasshopper.
DIVA uses Radiance, a free environemtal simulation software which you can download and install to run alongside Ecotect.
Radiance is more precise than Ecotect and can be used for Daylight studies, producing extremely accurate renders.
DIVA was written by Jeff Niemasz, a Harvard GSD student, as part of his masters project on re-visiting the aqua tower by Studio Gang.
You can register to the DIVA for Grasshopper group on the forum and follow the tutorial on installation (See videos below).

Nathan Miller, creator of Slingshot has used Kangaroo and his own plugin on Grasshopper to import his Facebook friends as a network of lines and applied different physical forces between them depending on the level of connectivity between friends.
Interesting way to start designing a building?
