**OpenFOAM 中级课程概览** 本课程旨在帮助学员克服 OpenFOAM 学习曲线的陡峭性，掌握解决工业级计算流体动力学 (CFD) 问题的实用技巧。尽管 OpenFOAM 功能强大，可用于设计各种复杂的工程设备，但学习过程中常遇到挑战，尤其是在湍流建模、复杂网格生成及网格行为与收敛性判断方面。 **课程重点：** * **深入理解湍流：** 探讨如何处理工业 CFD 中常见的湍流问题，将“艺术”与“科学”相结合。 * **高级网格生成技术：** 学习如何创建适用于复杂几何体（如战斗机机身、涡轮叶片）的网格，超越简单的网格方法。 * **网格行为与收敛性：** 掌握如何评估和确保计算结果的可靠性，即使缺乏现有解决方案用于对比。 **课程目标：** 通过本课程的学习，学员将能够独立解决更贴近实际的 CFD 问题，培养在面对实际工程挑战时反复使用和快速掌握新技能的能力。本课程将提供一系列通用且关键的 CFD 技能，为学员在工程领域的职业发展奠定基础。 **重要声明：** 本课程并非工程学位的替代品，也不构成专业咨询。购买本课程即表示学员理解并同意，课程讲师对因课程内容或师生沟通产生的任何争议、索赔、损失、伤害或损害概不负责。
The results are in - OpenFOAM can solve all the major industrial CFD problems that established competitors can. The power to design anything from jet airplanes and engines to pipes and heat exchangers is a simple download away. Unfortunately, as I learned the first time I used it, OpenFOAM has a very steep learning curve. Having learned the basics several years ago I quickly realised just how complicated CFD could get. Even though I knew how to set up a case and use blockMesh with some simple solvers it wasn't always clear how to do realistic problems with knowledge of the basics. The principle difficulties were:- Turbulence: all the really interesting flows included some aspect of this and it's often more art than science!- Meshing: simple meshes can't account for fighter jet bodies or turbine blades, I knew there must be a better way.- Mesh Behaviour and Convergence: without solutions with which to compare I never knew whether I could trust my results.I made this course with my younger self in mind. It's these things, among other tips and tricks, that gave me the most trouble in practice and which require the most experience/correct techniques to do well. The aim of this course, by its end, is to show you how to do this. There are many specialist topics that we can't cover and to learn CFD to an industry standard (where salaries past $100,000 a year are not unusual) could easily span a PhD and many years experience. Even so, there are a few general skills you will need again and again when you face practical problems in CFD. If you can master these, in my experience, you can pick up a lot of the rest as you go and quickly acquire the skills that are already propelling modern engineering into the future.Disclaimer:This course is not a substitute for a degree in aerospace engineering or specialist consultancy, by purchasing this course you agree that the course instructor is in no way liable for any disputes, claims, losses, injuries, or damage of any kind that might arise out of or relate to the content of this course or any supporting communications between instructor and student.
