Optimization was a theme running throughout the 2015 Automotive Simulation World Congress organized by ANSYS last week in Detroit. We attended sessions on topology, structural, aerodynamic, adjoint, multi-objective and multidisciplinary optimization that ranged across all the conference tracks—Powertrain, Body & Interior, Chassis, Electrification & Electronics.

With increasing life expectancies, the number of femoral fractures among elderly patients due to osteoporosis is expected to rise. To restore mobility in these patients as rapidly as possible, fracture treatment that takes into account the material properties of osteoporotic bone is essential. Continue reading
Optimizing turbofan designs is challenging because of the need to deal with both aerodynamic and structural performance. While designing a fan with high performance and efficiency is important, strength and reliability of the structure are also critical. Further, integrating parametric CAD, CFD and stress analysis is not a trivial task and usually takes extensive effort.
In this project SmartDO and ANSYS were utilized together to optimize a turbofan. The technical services team at SmartDO’s developer, FEA-Opt Technology, helped the customer build a parametric model with ANSYS DesignModeler, construct the CFX and mechanical analysis block, and integrate SmartDO with ANSYS Workbench. SmartDO was able to increase the mass flow of the fan by almost 14% while slightly reducing the maximum stress under aerodynamic and structural loading. These results showed promising possibilities for further design development. Continue reading

Automating the search for solutions to engineering problems can take either of two broad approaches: design exploration or design optimization. Practitioners making technology choices need to understand which tools do one, which do the other, and which approach best fits their needs. A global roster of commercially available design exploration and optimization software appears at the end of this post. Continue reading
