Kiwi3D
ADDON. Version 0.4.0. Released on 2020-01-31. Provides 50 components. Created by Kiwi!3D Team. Features 4 video tutorials.
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).
