In a new series, we are featuring our partners and the work they do with us in the simulation field.  Our first featured partner, the Simpleware™ Product Group at Synopsys, provide software solutions for Abaqus customers. In this project, sports manufacturer ASICS used Simpleware software and Abaqus to build a high-quality model for optimizing running shoe design.

This post was written by Jessica James, Business Process Analyst at Synopsys’ Simpleware Product Group.

ASICS uses computed tomography (CT) data and Synopsys Simpleware™ software to create 3D computational models for better understanding the role of stability in running shoes. Optimizing with simulation reduces the risk of lower extremity injuries for runners, as well as enhancing performance and reducing the risk of future manufacturing errors. Sole structure and heel eversion angle are particularly important for understanding stability and the overall performance of a shoe during running.

Alongside experimental methods, models created in Simpleware software for export to SIMULIA Abaqus simulation tools help ASICS reduce prototyping time and costs, as well as manufacturing waste. The methods developed by this project demonstrate the compatibility between Simpleware software and Abaqus for image-based simulation.
