课程名称：如何开始使用OpenFOAM 课程概述：在进行计算流体动力学（CFD）模拟时，结果必须与实验数据进行验证，不能盲目依赖数据。本课程将带您了解使用OpenFOAM进行简单CFD问题模拟所需的基础知识。课程内容包括几何准备、网格划分（使用Salome）、求解过程（利用OpenFOAM求解器）以及结果的后处理（使用Paraview）。这些软件均可免费获得，无需任何许可费用。 CFD技术有助于降低产品成本，通过在原型测试阶段节省时间和金钱。利用CFD技术可以快速进行原型测试，从而预测产品的未来表现，并在实际制造阶段之前发现并修正任何缺陷。这是一项年轻的技术，预计在不久的将来将大幅增长。 在课程中，您将能够根据给定几何的尺寸绘制CAD模型，并了解如何在Salome中对几何体进行网格划分，以获得适当的结果。网格大小对结果的准确性起着重要作用。此外，边界条件的假设也是CFD模拟中的一个关键方面，必须在CFD边界条件中正确实现真实生活条件的再现。最后，良好的结果后处理有助于将您的结果成功地传达给非技术人员。
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 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 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.
