Ivy is a small parametric design tool to explore simple system composed of :

• a doubly-cruved shell
• two linear actuators

This tool is embeded in a Rhino & Grasshopper plugin and allows to :

• define a topology (shell + 2 actuators)
• define a discrete grid of shapes that conform the given topology
• define a discrete grid of actuation (extension/shrining of actuators)

Deformations and stresses are computed for each grid node (both topology and actuation space) via Abaqus. Models are launched with a combination of .inp and .py files. Results are stored in a .db file via SQLite. Results can be imported back into Rhino & Grasshopper for further benchmarking and analysis.

Mainly, this tool is provided to compare environmental performances of shading devices and find some optimal solutions of efficient shading.
