使用变量和常量 std::cin不要用endl e.g. 下面写法是错误的 1cin >> typeNUmbe >>endl; 以上写法会报错！！！ 在C++中，变量名可包含数字和字母，但不能以数字打头。变量名不能包含空格和...

使用 std::cout 显示一行消息，std::endl 命令cout换行,作用就相当于\n ++i vs i++ ++i will increment the value of i, and then return the increment...

We get to that point, c++, this chapter mainly introduce parts of c++, and understand them with many code example.

We recall the continuity and Euler momentum equations in Eulerian form, derive the material derivative \(\mathrm{d} \mathbf{v} / \mathrm{d} t=\partial_t \mathbf{v}+(\mathbf{v} \cdot \nabla) \mathbf{v}\), and explain how Eulerian field descriptions relate to Lagrangian particlebased descriptions via \(\rho(\mathbf{x}(t), t)\).

This note primarily delves into incompressible flow momentum equation and Surface of water waves and boundary condition and Variational Formulation.
