PROCEDURE

1. Setup a form finding task. Only displacement is available to analyse for form finding process 2. Input the surfaces as membrane with prestress
3. Input the surface edge as prestressed cables
4. Input the brep vertex as supporting points
5. Preview the analytic model
6. Run the Kiwi solver
7. Preview the processed model

This exercise is using Grasshopper version 1.0.0007

01. Linear Analysis

Andreeq Bunica 8.2. Kiwi!3D, Physics Simulation & Structural Analysis

8.2.01. linear analysis

Date published: August 29, 2022

DESCRIPTION

Kiwi!3D is a structural analysis and form finding plugin that processes NURBS surfaces without the need of meshing. It integrates Iso-Geometric Analysis (IGA), which uses NURBS as basis functions for its Finite Elements.

PROCEDURE

1. Setup a linear analysis task and pick the attributes to analyse
2. Input surface as the base shell. Surfaces that share an edge will automatically be connected.
3. Define the shell material by selecting from the material library
4. Define curves as beams to support the structure
5. Define beam cross sections
6. Define supporting points
7. Define supporting curve
8. Define dead load on the surface
9. Preview the analytic model
10. Run the Kiwi solver
11. Decompose the model to rebuild the surface
12. Preview the z direction deformation
