Isogeometric Analysis (IGA) - Meshfree FE for Grasshopper
Support Email

Kiwi!3D enables the integration of Isogeometric Analysis (IGA). The special characteristic of IGA lies in the usage of Non-Uniform Rational B-Splines (NURBS) as basis functions for the Finite Elements. Hence it allows to run simulations directly on NURBS without the need of meshing.

Kiwi!3D includes a isogeometric Shell, Membrane, Beam and Cable element. It is able to handle Trimmed Surfaces as well as Coupled Patches (multi-surface models). You can run Linear as well as geometrically Non-linear Structural Analysis problems. Also it includes Form Finding for tensile structures (Updated Reference Strategy). 

For more information, also on the Theory of IGA and also Online Tutorials, see our website:

Please Note: The current state of the plugIn is work in progress. 

Have fun!
