Case Study: University of Leeds achieves a lightweight, topology-optimized exoskeleton for the LAVA Bionic Tower with Altair OptiStruct

University of Leeds - Customer Case Study

The University of Leeds faced the challenge of generating a free-form, lightweight exoskeleton for LAVA’s proposed Bionic Tower and tasked graduate James Kingman to explore topology optimization as a conceptual design tool. To do this, the team used Altair’s HyperWorks suite—specifically the OptiStruct solver—to bridge architectural vision and structural engineering requirements for an organic, material-efficient high-rise envelope.

Using LAVA’s CAD model, Kingman created a ~100,000–element finite element model in Altair HyperWorks and ran FE-based topology optimization with OptiStruct (element size ~1 m); studies typically completed in under 90 minutes on a standard desktop. Altair’s tools produced clear, actionable forms—root-like geometries under gravity and skeletal patterns under wind—enabled sensitivity studies by varying volume fraction, identified critical load paths, and demonstrated improved structural feasibility, precise load-bearing prediction, and rapid design exploration for architects and engineers.
