Collaborative multidisciplinary design optimization in the automotive industry

Collaborative Multidisciplinary Design Optimization in the Automotive Industry is a white paper just released by ESTECO detailing how Ford achieved “streamlined, multi-user design process management by expanding its MDO approach at [the] enterprise level with ESTECO’s collaborative web-based environment, SOMO.”

The accomplishments of Ford and ESTECO documented in this paper reinforce our long-held view that 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. See Design space exploration: Institutionalizing the practice and Ford adopts ESTECO’s SOMO to institutionalize enterprise MDO.

The new paper centers on two case studies. The first documents how Ford combined “multi-domain, simultaneous analysis and optimization with advanced mathematical tools that enable consistent computational resource savings,” while the second “looks into the extension of the collaborative optimization approach to the ONE Ford core platform system and targets a wider design scope.” From the white paper: 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

RBF mapping of electromagnetic loads onto FEM models: DEMO TF coil system example

New paper available for download: A new meshless approach to map electromagnetic loads for FEM analysis on DEMO TF coil system, Marco E. Biancolini et al. Highlights: Generation and mapping of magnetic load on DEMO using radial basis function. Good agreement between RBF interpolation and EM TOSCA computations. Resultant forces are stable with respect to the target mesh used. Stress results are robust and accurate even if a coarse cloud is used for RBF interpolation.

NAFEMS webinar—Democratization: Accessibility

NAFEMS webinar—Democratization: Accessibility, Oct. 27, 11:00 am EDT. Speakers: Dr. Dennis Nagy, BeyondCAE; TBA, BWAY Corp. Most existing general-purpose simulation tools are bound to a user’s desktop. While some of these tools are now being made available on the cloud, this process has been slow to gain traction for various reasons (e.g., ease of running graphics-intensive and complex applications on a desktop). Simulation apps are now beginning to make their appearance on both internal and external/public cloud platforms, allowing users to access these simple-to-use apps easily from anywhere and on their mobile devices. Furthermore, it is critical that a user also be able to access the required amount of computing hardware remotely. While a few (hardware) cores may suffice, there are situations when access to a large number of connected cores becomes essential (e.g., high run count for automated design exploration). In this webinar, an expert presentation and two end-user case study presentations will explore this topic further, demonstrating practical examples of simulation apps accessible on the cloud, and the ROI that the companies have experienced.

Improved prediction of organic-molecule thermodynamic parameters with surrogate modeling

solventAccurate calculation of the solvation parameters of organic molecules, important in many aspects of research in the pharmaceutical and agrochemical industries, is a longstanding challenge in computational chemistry. For example, many of the pharmacokinetic properties of potential drug molecules are defined by their solvation and acid-base behavior, which can be estimated from their hydration free energies. Solvation, also sometimes called dissolution, is the process of attraction and association of molecules of a solvent with molecules or ions of a solute; as ions dissolve in a solvent, they spread out and become surrounded by solvent molecules.

Autodesk Research Project Dreamcatcher: Pushing the limits of generative design

Project Dreamcatcher is Autodesk Research’s initiative to explore and expand the limits of generative design through the power of cloud computing, natural-language input, pattern-based problem description and AI-assisted design space visualization. Describing Dreamcatcher as an “experimental design platform with focused research probes into generative design systems,” Autodesk explains the spur for this work: “Recent advancements in artificial intelligence and the simulation of complex phenomena have enabled software to play an active, participatory role in the invention of form.”

At first glance this may look like topology optimization meets Invention Machine. But of course it’s much more. A goal-directed design system, Dreamcatcher’s objectives are summarized by Autodesk: “The Dreamcatcher system allows designers to input specific design objectives, including functional requirements, material type, manufacturing method, performance criteria and cost restrictions. Loaded with design requirements, the system then searches a procedurally synthesized design space to evaluate a vast number of generated designs for satisfying the design requirements. The resulting design alternatives are then presented back to the user, along with the performance data of each solution, in the context of the entire design solution space.” Continue reading

NAFEMS webinar—Democratization: Usability

NAFEMS webinar—Democratization: Usability, Oct. 1, 11:00 am EDT. Speakers: Chad Jackson, Lifecycle Insights; Michael “Zack” Eckblad, Intel. For non-experts to be able to run sophisticated simulations, it is critical that simulation apps be highly usable, speaking the language of the user and not the simulation expert. While there has been significant progress in making general-purpose simulation tools easier to use, they are, almost by definition, mostly used only by the experts. Meanwhile, “non-experts” continue to find that they are seldom able to use these tools safely, and must defer to the experts. In this webinar, a presentation by Chad Jackson and a case-study presentation by Michael “Zack” Eckblad of Intel explored this topic further, demonstrating practical examples of simulation apps at work, and the ROI experienced.
