Investigating Aeroelastic Performance of Multi-MegaWatt Wind Turbine Rotors Using CFD
Recent trends in wind power technology are focusing on increasing power output through an increase in rotor diameter. As the rotor diameter
increases, aeroelastic effects become increasingly important in the design of an efficient blade. A detailed understanding of the fluid elastic
coupling can lead to improved designs; yielding more power, reduced maintenance, and ultimately leading to an overall reduction in the cost
of electricity. In this work, a high fidelity Computational Fluid Dynamics (CFD) methodology is presented for performing fully coupled Fluid-
Structure Interaction (FSI) simulations of wind turbine blades and rotors using a commercially available flow solver, AcuSolve. We demonstrate
the technique using a 13.2 MW blade design.


Faster Design Changes with HyperWorks’ Morphing Technology
In the development of engine components PSA determines the lifetime of the intake manifold with a complex thermo mechanical calculation. Since the development process is distributed between PSA itself and a supplier, a design change of the intake manifold takes three weeks to be evaluated. For the supplier it has always been hard to correctly interpret the design improvements suggested by the PSA CAE engineers. Due to the three weeks of time, the iteration between OEM and
supplier takes, and because the overall development time is limited, the process just allowed a few design changes. Therefore the design of the manifold can become a critical task in the
engine development. With HyperWorks’ morphing technology (HyperMorph) it is possible to quickly implement design changes and hence to avoid intermediate CAD changes. With this process, only a single final CAD revision is needed when all improvements have been done. The new
workflow with HyperWorks’ morphing technology allows for a much faster evaluation cycle of two days instead of three weeks with the former process.

在发动机部件的开发中,PSA确定进气歧管复杂的热寿命计算。 由于开发过程在PSA自身和供应商之间是分布式,一个进气歧管的设计变更的评估需要三周。对于供应商来说,一直很难正确诠释PSA CAE工程师提出的设计改进建议。由于OEM和供应商之间的迭代需要三周时间,而整体开发的时间是有限的,设计流程中就只限少量设计变更。因此,该歧管的设计可以成为发动机开发的关键任务。HyperWorks的网格变形技术(HyperMorph)可以快速实现设计的变化,从而避免中间CAD的变化。在这个过程中,只有一个单一的最终CAD需要修改,而所有改进都已完成。HyperWorks的网格变形技术的新流程实现了更快的评估周期,从原先的三周缩短到两天。

Improved Mechanical Performance and Reduced Cost of a Solar Panel System with HyperWorks
HyperWorks proved to be exceptionally valuable in Luxon’s work for a major producer of a large-scale industrial panel system, which measures approximately 50 x 70 feet and rotates to track the sun. The company had a system in production but sought to lower the cost of manufacturing. Additionally, Luxon’s customer wanted to expand the geographic locations where the system could be installed successfully, so it asked Luxon to develop
a more robust support structure to ensure that the system would survive the seismic,
wind and snow loading that the product was likely to encounter in various parts of the world.


Consideration of uncertainties in forming simulation using HyperWorks
This was a 2013 European ATC presentation given by Markus Reinert from DTE Werkzeugtechnik GmbH & Co. KG. In the automotive industry, the lightweight is an increasingly important issue. This leads to the increased use of high strength steels and aluminum. These materials decrease the process capability of forming of many automotive components than conventional materials. It becomes more difficult to predict the feasibility of CAE methods.

Prediction of warpage in welded assemblies
This was a 2013 European ATC presentation given by Dr. Amin Sedighiamri from SABIC. Long glass fiber reinforced polypropylene (PP-LGF) is a material often used in semi-structural automotive components, such as front-end module carriers, door modules, dashboard carriers and hatch back doors. Main process for the production of these parts is injection molding, which generates complex glass fibre length and orientation distributions during processing.

Sequentially Cold Forming Simulation of Complex Shaped Heavy Plates
This was a 2013 European ATC presentation given by Dipl.-Ing. Steffen Garke from Universität Rostock.

DSHplus and AcuSolve - Fluid Power System Simulation Hand in Hand
This was a 2013 European ATC presentation given by Dr. Heiko Baum from FLUIDON Gesellschaft für Fluidtechnik mbH. Today the dynamic behavior of complex fluid power systems is typically simulated with 1D system simulation programs such as DSHplus. But, if accuracy requires modeling details at component level this technique comes to its limits. The representation of pressure losses of complex flow channel geometries, such as the bores in hydraulic manifold of heavy machinery or the customized pipe layouts in automotive applications or aerospace applications, cannot be achieved with a series connection of 1D system components.

Coupled thermal and structural analysis can be used to predict potential problems due to either material temperature thresholds or mechanical stresses.

汽车开发,把设计结果和突破性的产品部件整合起来,也给学生提供了汽车设计和工程动手体验。Deep Orange项目是CUICAR的一部分,CUICAR更大的战略重点是进行跨学科研究,应对采用高级汽车设计技术和产品创新所带来的的行业和社会挑战。

QIMR Case Study: Altair and Dell Improve HPC Capabilities for Leading Research Institute
Queensland Institute of Medical Research (QIMR) is using PBS Professional on a Dell cluster to improve HPC computing. According to the CIO, “Everyone has benefited from this installation. Researchers can do things they couldn’t do before, like running jobs multiple times or utilizing larger data sets, to achieve outcomes they couldn’t otherwise get. It’s pretty easy to see the value."

PBS Professional 助力QIMR提升 HPC 能力和支持高质量的研发能力
澳大利亚昆士兰医学研究院 (QIMR) 利用 PBS Professional管理Dell多核服务器集群来改善HPC计算效率。CIO指出, “每个人都得益于该系统的使用。我们的科学家现在可以提供更快、更准确的科研成果。我们同时能够处理更多的数据,并且更加迅捷。研究人员还可以做很多以前无法完成的事情,这套系统带给我们的价值显而易见。”

Smart Multiphysics Solving for Structural Responses based on Fluid Temperature Loading

BiggerBoat Solutions Makes Waves in Auto Industry Using HyperForm to Cut Die Development Costs and Time
When the auto industry crashed in 2008
and the tool shop where Jay Weiner worked
closed its operations, he started his own
company, called BiggerBoat Solutions Ltd.
He carries out metal-forming simulations
for major tooling suppliers and originalequipment
manufacturers. With 15 years
of experience in tooling design, Weiner and
his Toronto-based practice offered a service
that no one else had perfected but that
was crucial to a key process in automotive
manufacturing: the simulation-based die
design for stamped sheet-metal parts.
