This workshop will investigate particle simulation as a form finding method. In this workshop we will observe how computational spring-mass particle systems can simulate natural forms determined by forces and material behavior. The general introduction and examples will be covered in the lectures and tutorials. Students will conduct hands-on analogue and digital experiments with the help of tutors to understand how kinetic forming forces, such as gravity, magnetism, wind and air pressure can act on different materials to induce forms. The tutorials will introduce techniques for form finding and simulation, modelling tools and digital fabrication methods for making models and prototypes. Students will explore several procedural or kinetic forming processes from the nature in which natural forces (gravity, magnetic, wind, flow,…) play crucial roles, and then turn them into kinetic forms.
