The Digital-Physical Feedback Loop: A Case Study (2012)
article⁄The Digital-Physical Feedback Loop: A Case Study (2012)
abstract⁄Kukje Art Center, Seoul’s new gallery designed by SOIL, features a totally bespoke chainmail mesh system submission note the authors are not affiliated with SOIL. A single sheet of complexcurved, tensioned mesh, made up of interlocking 40mm diameter stainless steel rings, wraps the building. This paper discusses the stages of a feedback loop process employed by the authors to refine a digital model of the mesh. The mesh’s perimeter attachment system does not prescribe ring locations, allowing the mesh to form find for itself during installation. As a result, the digital model must capture the behavioral tendencies of the mesh as it negotiates the building’s geometry. Paramount in meeting this challenge was the use of physical mockups. At each stage of the feedback loop process, the working digital model was used to develop a physical mockup of increased scale and complexity, and this mockup was used to refine the digital model. Ultimately, the model output of a mesh relaxation algorithm was used as the basis for engineering simulations and predictions of the mesh vertical ringcount needed at specific locations around the building. Mesh vertical ringcount predictions are validated relative to a 11 mockup and the installed Kukje Art Center mesh.
