In this tutorial, we build a modelling, simulation and analysis workflow for unstrained 3D gridshell structures using Blender and OpenSeesPy.

This is the second part of our gridshell analysis series; in it, we'll build a workflow that allows us to digitally re-create the classic hanging chain form finding models used to identify the optimal shapes of gridshell structures.

We'll use Blender for 3D modelling and form finding simulation and OpenSeesPy to evaluate the stresses developed within the form-found structure.

After completing this tutorial, you'll have a good understanding of how to build a modelling, simulation and analysis workflow for unstrained 3D gridshell structures.
