课程名称：学习OpenFOAM计算流体动力学（水平3） 课程概述：本课程旨在教授您使用OpenFOAM进行简单计算流体动力学（CFD）问题仿真的基础知识。请注意，CFD结果在依赖之前，必须通过实验数据进行验证。课程将涵盖以下内容：使用FreeCAD和Salome进行几何体准备；利用Salome和snappyHexMesh进行网格生成；使用OpenFOAM求解器进行求解；以及使用Paraview进行结果后处理。所有这些软件均可免费使用，无需许可费用。 CFD有助于通过减少原型测试阶段的时间和费用来降低产品成本。借助CFD技术，快速原型测试可以预测产品的未来表现，从而提前发现并修正产品缺陷，避免在实际制造阶段出现问题。这是一项年轻的技术，未来有望实现显著增长。 通过本课程，您将能够根据给定几何体的尺寸绘制CAD模型，学习如何在FreeCAD中绘制CAD模型，并利用Salome对几何体进行网格划分以获得合适的结果。您还将学习如何设置snappyHexMesh，了解网格大小在决定结果准确性方面的重要性。同时，边界条件的假设在任何CFD仿真中也是一个重要方面，真实条件的复制必须正确实现。最后，良好的结果后处理可以帮助您将结果成功传达给非技术人员。
Note - CFD results always need to be validated with experimental data before blindly relying on them.This course will take you through all the basics required in order to simulate simple CFD problems using OpenFOAM.Geometry preparation will be covered using FreeCAD and Salome.Meshing will be covered using Salome and snappyHexMesh.Solving will be covered using OpenFOAM solvers.Post-processing of results will be covered using Paraview.All these software are available for free without any license costs.CFD helps to reduce the cost of products by saving time and money in prototype testing phase. Rapid prototype testings can be done by using CFD technology to predict the future behavior of the product. It enables us to foresee any shortcomings in the product and rectify them before the actual manufacturing phase of the product. This is a young technology and can grow substantially in near future.You will be able to draw CAD models using the dimensions of any given geometry. Then you will understand how to draw CAD model in FreeCAD and mesh the geometry in Salome to get appropriate results. You will also learn to setup snappyHexMesh. Mesh size plays an important role in deciding the accuracy of your results. Assumption of boundary conditions is another important aspect in any CFD simulation. Replication of real-life conditions must be correctly implemented in the CFD boundary conditions. Finally good post-processing of the results helps you to deliver your results successfully to the non-technical.
