一缸水收到冲击的VOF分析

fangdian

发一个例子，一缸水收到冲击：
代码如下：

不知对不对？呵呵

好好学习学习

aba_sim

DELX = 0.2                 ! X spacing
DELY = 0.05                ! Y spacing
这两句看不懂。

aba_sim

做成三维的可以吗？我现在正在做这个。不知从何下手，请版主指点。rmw@sqc.edu.cn

fangdian

三维的vof貌似ansys不支持。

DELX = 0.2                 ! X spacing
DELY = 0.05                ! Y spacing
这两句看不懂。 ...

就是定义两个变量

aba_sim

我查不到语句中有de这个命令，能详细解释下？先谢了。

fangdian

没有这个命令，DELX = 0.2只是表示将0.2赋给变量dexl,这个变量名是自己定义的，随便定义的，后面网格划分时用了。

做流体还是得看fluent啊！要不然ANSYS不会去收购fluent。
