After the heavy-lifting of the previous section, we’ll tackle something a little less intensive in this section. We’re going to build out the data visualisation that brings our analysis results to life.
Without an intuitive visualisation, it’s very hard to derive any value from our solver’s output so far. So, we’ll focus on developing an information-dense visual representation of the behaviour of our structure.
What we cover in this section will have a lot in common with previous DegreeTutors courses. This time, in addition to some aesthetic improvements, we’ll implement a feature that allows us to ‘step- through’ the converged stages of our solution. This allows us to visualise how our structure evolves into its final state.
In this section, you’ll pick up a lot of plotting and structure-visualisation tips and practices that you can propagate to your other work.

Non-linear Finite Element Analysis of 2D Catenary & Cable Structures using Python
Build an iterative solution toolbox to analyse structures that exhibit geometric non-linearity due to large deflections.
After completing this course...
- You will understand the concept of geometric non-linearity and when it should be considered.
- You will understand how to modify the axially loaded element stiffness matrix to account for large deflections and changes in geometry.
- You will have implemented a Newton-Raphson iterative solution algorithm that seeks to converge on the deformed state of the structure.
- You will have a workflow that leverages open-source modelling tools in Blender to quickly generate the initial structural geometry.
