swaying motion
Hi,
I am trying to generate a 2D sway motion of a fixed box. I just wondering if its ok to simulate the box by using moving boundary or we should define the box as floating box with fix z-displacement while moving the x-axis.
Somehow, when I tried to simulate the box as moving boundary, the repulsive forces of the boundary box push away the fluid particles near the box. When the fluid particles are too close to provide adequate repulsive forces, they will cluster together and instability can be observed in the vicinity of the box.
Do you have any comments on this?
Thank you.
