课程名称：从零开始的OpenFOAM（一级） 课程概述：本课程将引导学员掌握使用OpenFOAM模拟简单计算流体动力学（CFD）问题所需的基础知识。课程强调CFD结果必须通过实验数据进行验证，以避免盲目依赖。学习内容包括：使用Salome进行几何体准备以及网格划分，使用OpenFOAM解算器进行求解，以及使用Paraview进行结果的后处理。所有这些软件均为免费及无许可证费用。 CFD技术可以通过节省原型测试阶段的时间和成本来降低产品的成本。利用CFD技术进行快速原型测试，可以预测产品的未来表现，帮助我们在实际制造阶段之前识别并修正产品的不足之处。这项技术仍较为年轻，未来有望得到显著发展。 课程内容包括：绘制任意几何尺寸的CAD模型，导入CAD模型至Salome并进行网格划分，以获得准确的结果。此外，网格大小对结果的准确性有重要影响，而边界条件的假设也是CFD仿真中的一个重要方面，必须正确模仿真实状况。最后，良好的结果后处理可以帮助学员有效地向非技术人员传达研究结果。
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.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 import CAD model in Salome and 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.
