Modelling and Analysis of Non-linear Cablenet Structures using Python and Blender

Learn how to combine parametric modelling, exploratory form-finding and iterative analysis techniques to simulate 3D tensile structures.

After completing this course...

  • You will be able to apply an iterative Newton-Raphson technique to solve for the non-linear behaviour of 3D cablenet structures.
  • You will be able to apply parametric modelling and simulation-based form finding techniques to generate cablenet geometry.
  • You will have developed a complete modelling, analysis and visualisation workflow for exploring these elegant yet complex structures.
