This plugin contains a set of customised Kangaroo2 grasshopper components with the scope of calibrating a number of goals with regard to structural properties.

This is particularly useful for the analysis of form-active structures (including cablenets and gridshells) that are typically characterised by their large deformations when subjected to external loads. The underlying position-based dynamics implemented in the Kangaroo2 solver inherently deals with this non-linear behaviour. This means that both form-finding and analysis can be performed within the Grasshopper environment using K2 and K2Engineering.

Even though the plugin produces accurate and meaningful structural results, the author cannot be held responsible for the output and it should therefore always be used in combination with another finite element analysis package for validation and documentation.
