看见别人推荐的步骤:
1、prerequisite, basic fluid dynamic knowledge
2、fluent help document
3、an introduction to computational fluid dynamics the finite volume method
4、notes on comutational fluid mechnics,teaching material of national university of singapore
5、Computational fluid dynamics with heat and mass transfer,patankar
个人意见是看你应用fluent的哪个模块,先按照相近的算例走一遍,然后了解有疑问的地方,最后推广到你的问题上。
