Vof sloshing simulation issue

navi · August 17, 2016, 01:13

hello everyone,
i am doing sloshing simulation in ansys 14, in cfx, i have seen tutorial and some help in ansys,
my doubt is, i need to give motion to tank but ,how, now i am giving motion in initial condition like u=3 m/s, but I guess I am giving that velocity to fluid not to tank, how to give tank a sinusoidal motion when there is a half filled fluid in tank,
please help me in this, and even if you guys have any tutorial about this or pdf ppt, please send to my mail navi.stuti@gmail.com

If you want to move the tank then you will need use moving mesh to move the boundaries and domain. It is quite simple, have a look at some of the moving mesh examples in the tutorials.

You can also do this by moving the gravitational vector, but this is a simplification which does not include all effects. But this is a very simple way of doing it.

I was talking about the CFX tutorials which come installed with CFX. Have a look in the documentation for details of what is available.
