| Altair Virtual Wind Tunnel 2019.0 x64 汽車風洞仿真軟件 |
Altair宣佈引入一款流程化且高精度的垂直應用程序HyperWorks Virtual Wind Tunnel™ ，專用於改善汽車行業中的風洞仿真。Altair公司在Garden Grove（美國加利福尼亞州）舉辦的年度“Altair北美地區技術大會”Americas Altair Technology Conference上宣佈了這一消息。
HyperWorks Virtual Wind Tunnel 充分利用高級網格劃分及高保真計算流體動力學仿真等多種 Altair 最先進技術，並採用直觀、高度自動化和流程化的工作流程與用戶界面，將車輛外流場性能的精度和速度預測推向新高。
外流場仿真在現代汽車設計中扮演著舉足輕重的角色。車輛的燃料消耗量、穩定性、發動機冷卻、駕駛室內部噪聲以及風擋刮水器的性能均與空氣動力作用息息相關。借助採用計算流體動力學 (CFD) 的風洞仿真，工程師可以對這些空氣動力載荷進行研究，並能減少車輛開發過程中所需的物理風洞測試。
“HyperWorks Virtual Wind Tunnel 基準測試表明，Altair 的技術與實際風洞結果非常吻合，”Altair CFD 技術副總裁 Farzin Shakib 博士表示，“我們可以預見，HyperWorks Virtual Wind Tunnel 的易用性、靈活性、精度和速度定會使其風靡整個汽車行業，並在建築設計與構造以及風輪機開發等其他需要進行外流場仿真的領域中掀起使用熱潮。”
該解決方案的核心便是行業領先的Altair CFD 求解器AcuSolve®，其計算速度快、擴展性強、功能強大且精度高的特點使之脫穎而出。借助 AcuSolve 先進的湍流建模技術，HyperWorks Virtual Wind Tunnel 能夠利用穩態及瞬態仿真對流場和氣流分離進行預測，從而更快獲取更加精確的結果。AcuSolve 所提供的行業頂尖流體結構耦合解決方案將結構的靈活性考慮在內，可實現更為真實、全面的汽車虛擬風洞仿真。
“AcuSolve 是我們進行外部空氣動力學仿真的首選解決方案。更具體地說，使用 AcuSolve 進行外流場仿真，可以更容易獲得更加精確的阻力測量結果。”工程仿真及諮詢公司 Lx Sim總裁 Geneviève Dutil 說道。
HyperWorks Virtual Wind Tunnel 的另一項優勢在於其高級網格劃分功能。HyperWorks Virtual Wind Tunnel 以強大的網格劃分技術為依託，提供了具有邊界層的快速、全自動非結構化網格劃分器。汽車外流場分析的體網格劃分（包括車身底板、發動機艙以及邊界層）在兩個小時之內即可完成。作為 HyperWorks Virtual Wind Tunnel 的核心，CFD 求解器不僅對單元質量具有較強的包容性，還能夠管理對於複雜幾何無法避免的嚴重失真單元。其他解決方案的網格優化步驟通常需要時間的集中投入，而求解器的靈活性便打破了這一常規，從而大大減少了網格劃分所需時間。
HyperWorks Virtual Wind Tunnel 不僅具有友好直觀的用戶界面，還提供了高度自動化的設置過程。仿真可從 HyperWorks Virtual Wind Tunnel 環境中輕鬆提交至高性能的計算系統中。

Altair Virtual Wind Tunnel 2019.0 |
Altair introduced Virtual Wind Tunnel 2019.0, a streamlined and high quality vertical application designed to improve wind tunnel simulation for the automotive industry.
About Altair Virtual Wind Tunnel. Leveraging several of Altair’s state-of-the-art technologies from advanced meshing to high-fidelity computational fluid dynamics simulation, and designed with an intuitive, highly automated and streamlined workflow and user interface, HyperWorks Virtual Wind Tunnel brings new levels of accuracy and speed in predicting a vehicle’s external aerodynamic performance.
External aerodynamic simulation plays an important role in modern automotive design. The vehicle’s fuel consumption, stability, engine cooling, interior cabin noise and windshield-wiper performance all are influenced by aerodynamic forces. Wind tunnel simulations employing computational fluid dynamics (CFD) allow engineers to study these aerodynamic loads and can reduce the number of physical wind tunnel test experiments required during a vehicle’s development process.
Central to the solution is AcuSolve, Altair’s industry-leading CFD solver that is highly differentiated by its speed, scalability, robustness and accuracy. AcuSolve’s advanced turbulence modeling technology enables HyperWorks Virtual Wind Tunnel to predict the flow field and flow separation using steady-state and transient simulation for faster and more accurate results. The best-in-class fluid-structure interaction solution from AcuSolve allows more realistic and comprehensive automotive virtual wind tunnel simulation by considering the flexibility of structures.
Another advantage of HyperWorks Virtual Wind Tunnel is its advanced meshing capabilities. Built on a powerful meshing technology, HyperWorks Virtual Wind Tunnel comes with a fast, fully-automated unstructured mesher with boundary layers. Volume meshing for an external automotive aerodynamics analysis—including the underbody, underhood compartment and boundary layers—can be completed in less than two hours. The CFD solver at the core of HyperWorks Virtual Wind Tunnel is highly tolerant of element qualities, with the ability to manage badly distorted elements unavoidable for complex geometries. The solver’s flexibility eliminates the time-intensive mesh optimization step often required with other solutions, dramatically reducing meshing time.
HyperWorks Virtual Wind Tunnel provides a friendly, intuitive user environment and a highly automated setup process. The simulation can be submitted easily to high-performance computing systems from within the HyperWorks Virtual Wind Tunnel environment.
In this video overview of Altair’s Virtual Wind Tunnel (VWT) used for external aerodynamic analysis. Topics will include model preparation, design changes using morphing, solver technology (Navier-Stokes) and shape optimization.
