这里只是按照python的使用形式上抽象一下,没有运算符重载,因为目前一切都不稳定,一切到了需要的时候才去做,按照敏捷开发的原则来。 在OneFLOW的Scalar里面加上这几句就可以了。 运行后输出的plot文件,用myplot.py绘图 有: 看上去和python的结果雷同,当然仔细对比要靠代码,不过那样太累,每一步还是步子小一点,有获得...

CFD Python, a.k.a. the 12 steps to Navier-Stokes, is a practical module for learning the foundations of Computational Fluid Dynamics (CFD) by coding solutions to the basic partial differential equations that describe the physics of fluid flow. The module was part of a course taught by Prof...
Python中的CFD实现 下面是一个简单的使用Python实现CFD的示例,利用有限差分法求解二维热传导方程。 importnumpyasnpimportmatplotlib.pyplotasplt# 定义参数nx,ny=50,50# 网格点数nt=100# 时间步数nu=0.3# 动粘度dx=2/(nx-1)# 网格间距dy=2/(ny-1)# 网格间距dt=0.01# 时间步长# 初始化温度场u=np.zeros(...
这段代码和文章国产CFD开源软件OneFLOW的 12stepsto Navier-Stokes的系列(2) 是一样的功能,但是架构发生变化。这些变化是为了未来迎接更大的冲击而准备。实际上这就是一种偏导数或者说拓扑重构。 偏导数是指,在其它的功能或者性能等等不发生变化的情况下,修改代码结构,参数接口。当然,所谓的其它方面不发生变化只是一...
