| NUMECA FINE/Acoustics 8.1 用於執行氣動-振動-聲學建模 |
精細/聲學-一個軟件包，用於執行氣動-振動-聲學建模。該應用為解決廣泛的氣動聲學和相關振動聲學問題提供了巨大的機會，從零件和機構設計階段的簡單評估計算開始，到復雜系統的詳細大規模分析結束。
精細/聲學的主要特點：
-各種裝置的氣動聲學和聲學計算：飛機發動機和發動機短艙、螺旋槳、對轉開放轉子、壓縮機、渦輪機、機身和機翼表面的噪聲、直升機螺旋槳、風力渦輪機、通風和空調系統、風管、汽車消聲器和排氣管螺旋槳等。
-各類設備的振動聲學計算：振動結構、NVH（噪聲-振動粗糙度；噪聲-振動-剛度）、水泵、船舶結構、吸聲板、發動機噪聲、聲疲勞等。
-使用HEXPRESS/Hybrid構建自適應網格。在NUMECA中實現的CAD準備模塊和並行網格系統生成任意幾何體上的保形網格。
-直接導入CFD網格並將CFD結果投影到聲學網格上。
-導入結構實體網格和強度分析結果（用於振動聲學問題）。
-大型聲邊界條件及等效聲源
-邊界條件的易用性和定義多個域的靈活性。
-基於CFD-RANS計算的各向同性湍流寬帶噪聲預測
-流動噪聲（DSNG）用於預測各向同性湍流產生的寬帶噪聲。基於CFD-RANS計算。
-各種計算算法的實現：有限元法（FEM）和邊界元法（BEM）。一個
-頻率響應求解器（有限元和邊界元共享FEM/BEM）用於模擬非均勻流中的聲傳播。
-Ffowcs Williams&Hawkings（FW-H）解算器實現了一種聲學模擬，以模擬由固定或旋轉的固體或可滲透表面發出的噪聲。
-本征值的確定（有限元法），用於評估材料的本征聲模式、耦合振動聲模式和吸聲。
-NUMECA-Fine/Turbo中非線性諧波分析的完全積分
-不同類型操作系統上每個階段（MPI）的完全並行性
-所需計算結果的完整可視化和數據導出
-靈活的可視化工具和處理結果

Description:
Fine / Acoustics - a software package designed to perform aero-vibro-acoustic modeling. The application provides great opportunities for solving a wide range of aero-acoustic and associated vibro-acoustic problems, starting from simple evaluative calculations at the stage of designing parts and mechanisms, ending with a detailed large-scale analysis of complex systems.
Main features of Fine / Acoustics:
-Calculation of aeroacoustics and acoustics for various types of devices: aircraft engines and engine nacelles, propellers, open rotors of counter rotation, compressors, turbines, noise of aircraft bodies and wing surfaces, helicopter propellers, wind turbines, ventilation and air conditioning systems, air ducts, car mufflers and exhaust pipes, propellers, etc.
-Calculation of vibroacoustics for various types of devices: vibrating structures, NVH (Noise-Vibration-Harshness; Noise - Vibration - Stiffness), water pumps, ship structures, sound-absorbing panels, engine noise, acoustic fatigue, etc.
-Adaptive meshes built using HEXPRESS / Hybrid. The CAD preparation module and the parallel meshing system implemented in NUMECA generate body conformal grids on arbitrary geometry.
-Direct import of CFD grids and projection of CFD results onto an acoustic grid.
-Import of structural solids grids and import of strength analysis results (for vibro-acoustic problems).
-Large set of acoustic boundary conditions and equivalent acoustic sources
-Ease of use of boundary conditions and the flexibility of defining multiple domains.
-Prediction of broadband noise produced by isotropic turbulence based on CFD RANS calculation
-FlowNoise (DSNG) is designed to predict broadband noise produced by isotropic turbulence. Based on CFD RANS calculation.
-Implementation of various calculation algorithms: finite element method (FEM) and boundary element method (BEM). A
-frequency response solver (sharing of finite and boundary elements FEM / BEM) is used to model sound propagation in the presence of an inhomogeneous stream.
-The Ffowcs-Williams & Hawkings (FW-H) solver implements an acoustic analogy to simulate noise emitted by a fixed or rotating solid or permeable surface.
-Determination of eigenvalues (FEM method) for evaluating eigen acoustic modes, coupled vibro-acoustic modes and sound absorption by a material.
-Full integration with nonlinear harmonic analysis in NUMECA Fine / Turbo
-The full parallelism in each stage (MPI) on different types of operating systems
-complete visualization of the results of calculations needed and exporting Data
-Flexible visualization tools and processing results
-A graphical representation of the spectra or the timing diagrams in the virtual microphones and knots)
-Averaged estimates to obtain sound power, impedance, intensity, etc. by element groups
-Representation in linear frequencies and 1/3 octave bands
-A, C weighted sound pressure levels (correction for the sensitivity of the human ear)
-3D view of the calculated acoustic fields and distributions
