Wind of change gusting through flow modelling


T


he RES Technical Group has completed a significant research project into the uncertainty associated with


wind flow models. The result of this research is a method to systematically calculate the wind flow modelling uncertainty of wind farm energy yields. This method is being released to the wider wind industry as an open-source software program called DeltaWindFlow. The company says the software’s


evidence-based method of wind flow model uncertainty calculation has many important applications, including the optimisation of wind resource assessment campaigns and financial risk analysis of wind farm projects. Peter Stuart, senior technical manager at RES Group, said: ‘DeltaWindFlow has proved indispensible at RES for quantifying uncertainty and appraising the benefits of instrumentation investments. By sharing this tool with the wider industry,


we are hoping other organisations can benefit in the same way.’ Wind flow modelling is the process


of predicting how the wind resource will vary in response to changes in terrain and surface roughness or obstacles. The output of a wind flow model is a ratio of wind speeds between two locations (commonly called the speed-up). DeltaWindFlow can be downloaded


from the download area of the RES website: www.res-group.com


Coupling promises improved powertrain performance LMS International, a provider of test and mechatronic system simulation, has announced a partnership with Hofer, the German powertrain system, component and service provider. After several years of cooperation, LMS and Hofer are consolidating a long-term relationship through wider deployment of the LMS Imagine.Lab


simulation tool – which is expected to further contribute to improved quality and time to market of Hofer’s products and services.


LMS will also benefit by further optimising its system simulation solution for powertrain through regular feedback from the undisputed technological expertise of Hofer’s

Autodesk Simulation DFM Autodesk Simulation DFM (Design for Manufacturing) software, described as the industry’s first injection moulding simulation software providing real-time feedback, has been launched. The CAD software plug-in is aimed


at providing designers of plastic parts with a faster and easier way to determine the impact of design decisions on manufacturability, cost and sustainability concerns. Based on Autodesk Labs technology also known as Project Krypton, Autodesk Simulation DFM integrates with Autodesk Product Design Suite software, and specifically

Autodesk Inventor software, and provides a complementary technology to Autodesk Simulation Moldflow software. It also works with Dassault, SolidWorks and PTC Creo software to support companies working in a multi- CAD environment. ‘With Autodesk Simulation DFM, designers of plastic parts can more easily create designs that are viable from a manufacturing standpoint, while helping ensure low costs and sustainability,’ said Robert Kross, senior vice president for design, lifecycle and simulation at Autodesk. www.autodesk.com

Maple 16 update


Maplesoft has enhanced its connectivity to major CAD systems with the launch of Maple 16, which supports Autodesk Inventor 2012, Solidworks 2012 and Siemens NX 8. By using Maple, CAD users determine the mathematical relationships between objects and how changes to object properties impact other objects in their design. Using the Maple programming language, built-in API commands and interactive technical document


environment, users can also create easy-to-use specialised tools for part reconfiguration and optimisation, to share with other engineers. In addition to CAD connectivity,


features like external calling, the OpenMaple API, web connectivity, extensive import and export tools and connectivity with other software are intended to make it easy to incorporate Maple into existing engineering toolchains. www.maplesoft.com
