stress 和grid deformation 的疑问
CFD-ACE中,在stress 和grid deformation 模块,边界条件上都有displacement,他们有什么区别?
no difference. when you run grid deformation model without stress, you can specify the displacement of one face, or node
具体什么意思?
the distance of the picked face moved
如果我要做一个题目,但是不知道它的displacement,那怎么设置?
you can specify moving velocity
一般液滴的内部压力设置在什么地方?
if you are using VOF module, you don';t need to specify the pressure inside the droplet, the solver will calculate it automatically.
other cases, you have to tell me what physical model you try to solve. |
