swaying motion

edited March 2015 in Old versions
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.

  • I have the same problem about instability in the vicinity of the a boundary, not sure what to do.
  • Please send your case to dualsphysics@gmail.com and we will try to run the case, observe the problem and look for a solution

  • Thank you. I will send ASAP.
