The latest release of Siemens’ STAR-CCM+® software for multiphysics computational fluid dynamics (CFD) simulation and analysis includes two new seamlessly integrated features which enable automated product design exploration and optimization. STAR-CCM+ version 12.04 introduces Design Manager, allowing users to easily explore multiple design options within their CFD simulations, and STAR-Innovate™ software, which uses the same proven design optimization technology found in HEEDS™ software – a technology Siemens obtained as part of its 2016 acquisition of CD-adapco. STAR-CCM+ is developed by Siemens’ product lifecycle management (PLM) software business, and is part of the company’s Simcenter™ portfolio, a robust suite of simulation and test solutions. "I firmly believe that single-scenario engineering simulations are about to become a thing of the past,” said Jean-Claude Ercolanelli, Senior VP of Product Management at Siemens PLM Software. “If you know how to use STAR CCM+ then you will instinctively know how to use Design Manager. This means that every engineer who installs STAR CCM+ v12.04 can now conduct design exploration studies with ease to discover better designs, faster."
Virtuelle Produktentwicklung bei Haushaltsgeräten – Durch Simulation Effizienz- und Funktionsanforderungen meistern
Neben dem Erhalt immer besserer Energielabels und dem damit einhergehenden Gewährleisten strikterer Effizienzkriterien stehen im Haushaltsgerätemarkt und bei seinen Produkten heutzutage vor allem das Erfüllen gesteigerter Endverbrauchererwartungen und Sicherheitsaspekte im besonderen Fokus. So ist für die Hersteller beim Design und der Entwicklung von Öfen, Kühlschränken, Waschmaschinen und Trockner nicht nur ein möglichst detailliertes Verständnis von dem thermischen Verhalten der Geräte erforderlich, um energieeffizientere Produkte entwickeln zu können, auch die korrekte Funktionsweise und...
As we move into the summer months, I am ever thankful that modern commercial aircraft systems have been developed to provide a safe and comfortable passenger experience. The Environmental Control System (ECS) is responsible for keeping the cabin at a comfortable temperature, pressure and humidity throughout the flight profile. This is done through a complex system of ducting, pressure regulators, heat exchangers and air conditioning components. Before the FAA can certify a new aircraft for commercial flight, the manufacturer has to be able to provide proof that the system can respond to situations where things go wrong.
Using CFD to evaluate ship hull performance in realistic sea conditions
Growing competition and increasing environmental awareness within the marine industry drives a continuous need for more efficient methods for the design of new vessels. Today, CFD is widely used to perform analyses of ship hulls in calm water, yielding results which can be used to quantify important parameters such as calm water resistance or propeller-hull interaction. However, calm water is usually far from the true operating conditions, meaning that understanding the performance in real sea states is of great importance. In many cases, the optimum design for rough seas differs...
Siemens’ STAR-CCM+® software, the industry-leading multiphysics computational fluid dynamics (CFD) tool, has achieved ASME Nuclear Quality Assurance-1 compliance. The addition of NQA-1 compliance in the rigorous ASME QA certification program ensures the code meets industry-standard requirements for nuclear industry customers in support of safety-related applications. STAR-CCM+ is developed by Siemens’ product lifecycle management (PLM) software business and is part of the company’s Simcenter™ portfolio of simulation solutions.
When my kids were younger, one of the favorite entertainment options at children’s parties was the balloon artist. These artists were able to make anything from a monkey to a pirate hat simply by twisting balloons together. Usually, but not always, you could tell what the animal or object was meant to be, but it would take the most imaginative child to see the multi-colored lumpy lion in front of them as the real thing. Whilst lions are not the most common shape for non-spherical DEM particles, should you have the need to model such a thing, previously your only option would have been the composite DEM particle and the result would have been much the same, a bunch of spheres of various sizes stuck together. All of that is set to change with the polyhedral DEM particle in STAR-CCM+® software version 12.04. Now you will be able to accurately model real objects, putting the corners back into your particles, by building or importing a realistic representation as a geometry part which then forms the basis of your particle. For many objects, this new polyhedral particle is less computationally expensive then a composite particle which can require many spheres to get close to a realistic shape. Polyhedral particles also provide a more efficient solution, reducing simulation time.
Simulation for safe and reliable oil and gas operations and maintenance
Ensuring safety during production and maintenance is critical to the oil and gas industry, while operational reliability and production assurance are key to operating a successful oil and gas production facility. This event will explore the role of simulation in two aspects of oil and gas, maintenance and production operations. We will have two presentations: Simulation Engineering: A Virtual Blow-Out Preventer Alistair Gill, Vice President (Advanced Engineering) Wild Well Control, will present how his team uses simulation of pipe freezing to assess how to perform safe mechanical repairs to...
WLTPガイドライン達成のための 車両空力シミュレーションと設計探査の活用ウェビナー
燃費およびCO2排出量測定の新しい試験法への移行に伴い、国連によって新たな「乗用車等 の国際調和排出ガス・燃費試験法(WLTP)」が策定されました。WLTPの狙いは、現実の走行 実態をより正確に反映し、全世界で排ガス試験の調和を図ることにあります。この新しい試験 法は2017年に始まり、全面移行の2018年まで段階を経て導入されます。 WLTPの主なインパクトの一つは、燃費と排出ガスの算出が車体、エンジン、トランスミッショ ンのみに焦点を当てたものではないというところにあります。設計者は、特別な仕様やそれら オプションの追加による重量の変更まで考慮に入れる必要があります。具体的に車両空力特性に 関しては、ベースラインとなる車両構成だけでなくすべての構成を考慮しなければならないため、 設計や試験により高い負荷がかかります。 本ウェビナーでは、このような負荷、コスト、ターンアラウンドタイムを低減する方法をご紹介 いたします。メーカーが、実形状のデジタルツインを活用して現実世界の試験条件をシミュレー トすることで、どのように燃費や排出ガスを予測すれば良いか、また車両を新しい基準に合わせ て最適化し、試作の前段階で厳しい環境規制を現実的に満たすことが可能となるかをご紹介いた します。 また、車両空力におけるCFDの現状を検証し、現実的にコスト効率を考慮しながら...
