summary 
This paper describes the relaxation of charged particles in order to create a pattern of voids based on a scalar field on any complex polygon mesh. A scalar field representing stress values or a greyscale image, can be used to create void patterns of aesthetic or structural character; all with full awareness of the materiality. Following relaxation, areas with low scalar values consist of large voids with a small distance between them. Areas of high scalar value consist of small voids with a greater distance between them. This research has been applied in the design of a sculpture at Oxford Brookes University, where stress data from Finite Element Software has been used for the automatic and rational distribution of holes.
