Next generation of PIDO: Noesis Solutions id8 transforms simulation-based engineering into objectives-driven engineering

Noesis Solutions NV, a pioneering developer of software technology for PIDO (process integration and design optimization), is extending its product portfolio with a series of next-generation application suites designed to transform simulation-based engineering into what the company characterizes as objectives-driven engineering. “Starting from product targets that outsmart competition,” Noesis explains, “such a process enables engineering teams to work their way back to the most critical design parameters and to engineer right first time.”

The first of these products, called id8 decide, is a new toolset for visualizing the design space. Far more than just an incremental refinement of existing functionality, this new software multiplies the value of Noesis’ Optimus software by radically strengthening and deepening users’ ability to achieve what Noesis terms “a clear vision of the design space.” On seeing id8 decide live in operation, we were impressed with the clarity and discoverability of functionality offered by its clean, up-to-the-minute graphical user interface, as well as advances at deeper levels of functionality—responses shared by beta users.

The beginning of Noesis’ transformation from a one-product company to a multi-product solution provider, id8 decide will be followed by future id8 application suites that, in similar fashion, will complement Optimus and step up its power through the addition of entirely new capability sets.

Collaborative design optimization

Design space exploration and design optimization are rapidly becoming strategic competencies that engineering organizations must master to remain competitive. To have strategic and not just tactical impact, design exploration and optimization need to be adopted and deployed within the framework of a collaborative, enterprise-wide vision.

To date, however, the tools and methods are too often implemented at only the department or workgroup level, keeping their impact limited and localized. This deployment pattern is rooted in the early history of design optimization, when the discipline consisted mainly of abstruse mathematical methods that could only be applied manually by small numbers of PhD-level specialists. But today the picture is different, thanks to the burgeoning number of software tools that make these powerful methods more broadly available to the engineering community. Continue reading

Smart optimization for robust optical performance in camera lens design

This information is excerpted from a case study published by Noesis Solutions. Access the complete case study here.

Besides providing the capability to shoot high-quality images, the development of new camera optics needs to deliver a product that is competitive in terms of price and weight. Geometry imperfections and clearances between the separate lens elements of photographic lenses typically reduce the quality and reliability of the manufactured product. To take into account the impact of these tolerances on product quality, engineers used Optimus from Noesis Solutions as part of their development process.

With Optimus, the engineers successfully combined both CETOL 6σ tolerance analysis software and CODE V optical design software into an automated simulation-based design process. This way the engineering team evaluated the impact of assembly tolerances for each of the individual lens tubes (defined in CETOL 6σ) on the optical performance of the camera lens (calculated by CODE V). The result is a photographic lens design which can be manufactured easily and cost-efficiently, yet reliably delivers the expected image quality. Continue reading

Multi-objective optimization of electric motor for increased drive torque and noise reduction

This article was first published by Noesis Solutions and can be downloaded here.

Optimus enabled the engineers to orchestrate ANSYS magnetic/structural simulations in exploring the design space and optimizing the motor design.

Engineers from Cybernet Systems took electric motor technology to higher quality and performance levels. Using Optimus from Noesis Solutions they optimized the design of an electric motor with interior permanent magnets (IPM) for maximum drive torque and minimum noise and vibration. Optimus enabled them to orchestrate ANSYS magnetic/structural simulations in exploring the design space and optimizing the motor design. The results of the multi-objective optimization were impressive: drive torque went up by 7% while lowering cogging torque by 35% and acoustic radiation by almost 6 dB. The approach opens up new opportunities for IPM synchronous electric motors used in (hybrid) electric vehicles, compressors and appliances. Continue reading

Maximizing aircraft economy through multidisciplinary winglet optimization

Winglets increase the lift generated at the wingtip by smoothing the airflow across the upper wing side near the tip. Winglets also reduce the lift-induced drag caused by wingtip vortices, improving the lift-to-drag ratio of the aircraft.

Executive summary—Wingtip devices are intended to reduce aircraft drag through partial recovery of the tip vortex energy. Fuji Heavy Industries (FHI) used Noesis Solutions’ Optimus to automate and couple FEM and CFD simulations to identify optimized winglet design configurations offering operational and environmental benefits. Optimus realized a 1.2% reduction in aircraft takeoff weight for a typical mission profile at 1G cruise speed. It achieved this by balancing the aerodynamic benefits and weight penalties of a passenger aircraft model integrating wing reinforcement to withstand winglet induced loads. Optimus’ design of experiments (DOE) and response surface modeling (RSM) capabilities helped FHI engineers understand the impact of winglet characteristics on aircraft performance up-front. Global design optimization enabled them to reduce the aircraft’s cruise drag by 4% and its takeoff weight by 676 kilograms, while respecting the shock induced separation (SIS) airflow constraint.

Design space exploration: Institutionalizing the practice

EVENT NOTICE—If you’re in the Detroit area, join Noesis Solutions’ free seminar April 9 on Innovations in Process Integration & Design Optimization. You’ll hear three perspectives on how this technology can help you streamline your simulation processes and identify benchmark product designs in less time, including a presentation by me on Innovative Uses of Optimization for Engineering Design Problems. Event and registration information here.

Achieving institutional adoption of design space exploration, design optimization and process integration is a crucial goal for engineering organizations working to establish these as strategic competencies, not just tactical. Too often implemented at only the department or workgroup level, the technologies and their attendant work processes need to be recognized and given backing as enterprise capabilities to have their greatest impact on engineering’s ability to advance corporate strategic objectives.

Model-based design optimization of a hybrid electric vehicle

Last week’s post surveyed the trend of integration between design exploration and optimization software and systems modeling and 0D/1D simulation tools. This week’s case study shows how the two technologies were used together in development of a new hybrid electric vehicle (HEV) to achieve the competing goals of improving fuel efficiency and meeting emissions targets.

Executive summary—A leading automotive OEM used Noesis SolutionsOptimus design optimization and process integration software in conjunction with Maplesoft’s MapleSim multi-domain systems modeling and simulation tool in developing the HEV’s combined electric and combustion propulsion system. Optimus was used to automate the traditional guess-and-correct simulation-based design process, its optimization algorithms efficiently directing the system simulation campaign to identify the best HEV configurations. Using Optimus’ capabilities for design of experiments (DOE), response surface modeling (RSM) and multi-objective optimization (MOO), engineers improved fuel efficiency by 21% and traveling performance (legal emissions compliance) by 15%. With MapleSim providing HEV modeling and Optimus controlling simulation workflow execution, the design optimization was accomplished in just two weeks. Continue reading

Model-based design exploration and optimization

Discussions of how to simulate early in product development fixate too often on FEA, overlooking the power of systems modeling and 0D/1D simulation for studying, exploring and optimizing designs at the beginning of projects, when product geometry is seldom available for 3D CAE but engineering decision-making can have its greatest impact and leverage on project success.
