课程名称：学习OpenFOAM CFD（Level 2） 课程概述：该课程强调CFD（计算流体动力学）结果在使用前必须通过实验数据进行验证，以确保其可靠性。课程将带领学员掌握使用OpenFOAM进行简单CFD问题模拟所需的基础知识。内容包括利用Salome进行几何体准备、使用Salome和snappyHexMesh进行网格生成、利用OpenFOAM进行求解以及利用Paraview进行结果后处理。所有这些软件均可免费使用，不需要许可证费用。CFD技术有助于通过节省原型测试阶段的时间和资金来降低产品成本。通过CFD技术，可以快速进行原型测试，预测产品的未来表现，从而提前识别并纠正潜在缺陷，避免在实际制造阶段出现问题。该技术仍处于发展阶段，未来有望实现显著增长。课程将教会学员如何根据给定几何体的尺寸绘制CAD模型，以及如何在Salome中对几何体进行网格划分以获得精确结果。网格大小对于结果的准确性至关重要，而边界条件的假设同样是CFD模拟中的重要环节，真实条件的复制必须在CFD边界条件中得到正确实现。最后，良好的结果后处理将帮助学员有效地将结果呈现给非技术受众。
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 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 mesh the geometry in Salome to get appropriate results. 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
