Mark West workshop attempted to simulate digitally parameters for formwork shells. The Shell is made with a piece of fabric and a tessellated pattern on the top of the fabric, which are considered as blocks. The blocks have a thickness and are separated between themselves with a specific distance. The parameters analysed in this case were the shape, such as triangle, square and hexagon, the block thickness and the separation distance between them. The resulting shells in each iteration were quantified as block deformation and edge deformation. In order to optimise the resulting shell simulations, the hexagon geometry was chosen to optimise the curvature and the structural properties. For this procedure, Inspire software was used. Equal forces and supports were applied to the chosen structure resulting in the area needed to be optimised. According to the this result, the tessellation pattern was changed. In Collaboration with Mark West, CAST founder, and the Royal Danish Academy of Art, Copenhagen, we participated to built a 1:1 model as well as building our own 1:10 model based on topological optimisation on fabric and brick patterns to create dome structures. The software used were Maya by Autodesk and Inspire by Altair.
