LayOpt is an interactive web app that allows users to rapidly identify the minimum volume layout (or ‘topology’) of a 2D truss.
A prototype version of the web app was commissioned as part of the BUILD-OPT research project, involving the Universities of Sheffield, Bath and Edinburgh and a number of industry partners, funded by EPSRC. The current Amazon Web Services version of the web app was developed by LimitState Ltd as part of a follow-on EPSRC/HEIF Knowledge Exchange project involving the University of Sheffield, Arup and LimitState Ltd.
LayOpt uses the LimitState:FORM optimization engine also employed by the LimitState:FORM interactive design optimization software and Peregrine, an optimization plugin for Rhino/Grasshopper. These software tools allow a range of real-world 3D problems to be tackled.
