**Coursera 课程总结：Ansys Fluent 实践与求解器精讲 (Class#4)** 本课程将深入探讨 Ansys Fluent 的核心功能，重点在于实践操作和求解器设置。 **Ansys SpaceClaim (建模)：** * 从零开始创建 3D 模型，掌握草图绘制、拉伸、混合、分割体、移动等工具。 * 通过装配模型进行实践，并学习图纸细节的绘制。 * **重点学习：** SpaceClaim 模式、"平面"概念、草图创建、建模工具、结构树的高级功能、显示选项卡。 **Ansys Meshing (网格划分)：** * 了解主要的网格划分方法，包括四面体网格 (Patch Conforming 和 Patch Independent) 以及六面体网格 (Sweep, Multizone, Hex dominant)。 * 学习如何录制网格划分过程。 * **实践目标：** 测试和比较不同网格划分方法生成的网格，包括： * 自动 (Tet Patch Conforming) * 多区域分解 (Multizone Decomposition for Sweep Meshes) * 自动 (Tet & Sweep) **Ansys Fluent (求解器)：** * 学习如何指定求解器类型（压力基、密度基），选择计算方法和控制参数。 * 掌握溶液初始化技术，并了解如何使用报告定义来监控收敛性。 * **深入讲解求解器选项卡：** 方法、控制、残差、初始化、计算部分和收敛标准。 * **实践与演示：** * **求解器类型：** 压力基、密度基 * **控制：** 松弛因子 (Under-relaxation Factor) * **求解方法：** Simple, Simplec, PISO, Couple * **初始化：** 标准初始化、混合初始化、FMG 初始化、从前一解开始 * **压力插值方法：** Standard, PRESTO, Linear, Body Force Weighted * **离散化方法：** 一阶迎风、二阶迎风、MUSCL、QUICK * **梯度插值方法：** Green-Gauss Cell-Based, Green-Gauss Node-Based, Least-Squares Cell-Based * **收敛演示 Demo:** Manifold Workshop * **重点解决：** * 离散化对结果的影响。 * 如何处理收敛问题。 * 残差收敛但报告图仍有变化时的处理方法。 * 如何充分利用报告定义。 本课程旨在通过丰富的实践案例，帮助学员熟练掌握 Ansys SpaceClaim 的建模能力、Ansys Meshing 的网格划分技巧以及 Ansys Fluent 求解器的设置和问题解决能力。
Ansys Space Claim(Creating Model)= Creating 3D Model from scratch with using tools such as sketch creation,pull, blend,Split body,move, do practice with assembly model, and detailing the drawings.Workshop Completion of this workshop will help to gain an understanding of: •Modes available in Space-Claim •The concept of "Planes" •Creating sketches •The available modeling tools •Advanced features in the Structure Tree •The display Tab Ansys Meshing( Meshing Method)= Learn difference between the Main Meshing method such as Tetrahedral(Patch Conforming and Patch Independent) and Hex Meshing(Sweept, Multizone ,Hex dominant) and learn how to recording the meshing Workshop This workshop will introduce different meshing methods available in ANSYS Meshing Objectives Testing and comparing the mesh generated by the different methods: Automatic (Tet Patch Conforming) Multizone Decomposition for Sweep Meshes -Automatic (Tet & Sweep) Ansys Fluent(Solver)=how to specify the solver and choose methods and controls, how to initialize the solutions, how to use the report definitions to monitor and judge converge and talk details in Solving Ribbon such as Method, Controls, residuals, initialization, Calculate section and converge criteria.Doing more practice with Workshop model section.Solver Type Pressure Based Density Based Controls Under-relacation Factor Solution Controls Solution Method Simple Simplec PISO Couple Initiliazation Standard Initialization Hybrid Initialization FMG Initialization Starting from a Previous Solution Interpolation Methods for Pressure Standard PRESTO Linear Second-Order Body Force Weighted Discretization (Interpolation Methods) First-Order Upwind Second-Order Upwind Monotone Upstream-Centered Schemes for Conservation Laws (MUSCL) Quadratic Upwind Interpolation (QUICK) Interpolation Methods (Gradients) Green-Gauss Cell-Based Green-Gauss Node-Based Least-Squares Cell-Based Converge Demo: Manifold Workshop = Solving -Effect of discretization What to do when convergence problems are encountered What to do if the residuals converge but report plots are still changing How to make full use of Report Definitions
