CHALLENGE -  Cummins is a corporation of complementary business units that design, manufacture, distribute and service engines and related technologies, including fuel systems, controls, air handling, filtration, emission solutions and electrical power generation systems. Appropriate and continual development of tools is needed to cover past, current and future potential failure modes as well as in aiding in the development of customer unexpected features that become delighters and future requirements. Deploying optimization tools and methods across the enterprise has been a key enabler for Cummins to continue our analysis centric culture maturation. 

SOLUTION - Cummins uses modeFRONTIER to facilitate “system-level” design optimization studies, quantifying the trade-offs across system-level performance to detailed component design. "Full" design space exploration means, for example, overhead system optimization:

  • 15000 designs evaluated over a weekend
  • Up to 15 nodes (360 cores) used for a single run
  • Utilized 32 nodes simultaneously over the weekend (768 nodes)
  • Evaluated 72 design points in parallel, running at the rate of ~1,000 designs per hour

BENEFITS - The future steps to accomplish the MDO cutlure shift requires to further develop​ people, tools, processes around: automation, optimization,  multiphysics, HPC usage, cross functional collaboration, reduced order models, robust design, systems engineering.​ All themes embodied by the vision for MDO at Cummins. modeFRONTIER is the tool to facilitate the vision by enabling engineers to reduce the "button-clicking" and facilitate the decision-making process, collaborate through different models and optimize spans across functional silos.
