Hi, I am trying to calculate dynamic behavior of accelerated liquid storage rectangular tanks in 2D model. rectangular tank partially filled by liquid is moving from left to right as sin wave acceleration. . Does anybody exaplain to me how i can set boundary conditions on the two vertical walls and the tank bottom (the tank is moving horizontally not fixed). Thanks,

you can set fixed wall conditions for them but the fluid is moving due to a specified acceleration.

I dont khnow if you have seen the tutorial: Gas tank sloching (I think that is your subject)

I can send it if you want neverless I have'nt the grid file
