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HyperWorksVirtualWindTunnel™,專用於改善汽車行業中的風洞仿真。Altair公司在GardenGrove(美國加利福尼亞州)舉辦的年度“Altair北美地區技術大會”AmericasAltairTechnologyConference上宣佈了這一消息。 HyperWorksVirtualWindTunnel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。 “HyperWorksVirtualWindTunnel基準測試表明,Altair的技術與實際風洞結果非常吻合,”AltairCFD技術副總裁FarzinShakib博士表示,“我們可以預見,HyperWorksVirtualWindTunnel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AltairCFD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,HyperWorksVirtualWindTunnel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LxSim總裁GenevièveDutil說道。 HyperWorksVirtualWindTunnel的另一項優勢在於其高級網格劃分功能。HyperWorksVirtualWindTunnel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HyperWorksVirtualWindTunnel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。 HyperWorksVirtualWindTunnel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HyperWorksVirtualWindTunnel環境中輕鬆提交至高性能的計算系統中。 關於Altair Altair的產品和服務通過優化對商業和工程信息的分析、管理和可視化,致力於增強客戶的創新力和決策力。Altair目前為私人所有,在全球擁有2000多位員工,分支機構遍及美洲、歐洲及亞太地區。憑藉其在產品設計、先進工程軟件和網格計算技術上28年的經驗,Altair不斷為各個行業的客戶創造競爭優勢。 AltairVirtualWindTunnel2019.0| AltairintroducedVirtualWindTunnel2019.0,astreamlinedandhighqualityverticalapplicationdesignedtoimprovewindtunnelsimulationfortheautomotiveindustry.
