Hi, I have changed the case of the DualSPHysics_v5.0\examples\main\05_SloshingTank\CaseSloshingMotion_Def.xml to a 3D model .But I get a particle leak just like the picture, it looks like a problem with the boundary condition settings? How can I fix it please?

You have to check where those particles are coming from.

You have to check if you have created all walls of the tank, etc

Check:

Particle resolution effect
Double check side walls being present
Add more layers of particles, i.e. 4 layers for each wall at a minimum

Kind regards

Thanks for your reply, it looks like the particles are leaking from the bottom of the box,

when the box is stationary everything is fine, but when the box is in motion the particles are leaked from the bottom.

And the 2D result has no such problems

This is the box I creat:

<setshapemode>real | dp | bound</setshapemode>

<point x="-0.45" y="-0.1" z="0" />0.0

</drawbox>

Thank you , I'll give it a try now

Thank you again, with your advice I have solved the problem by using multiple layers of walls, just one layer of walls did not look feasible in the 3D simulation

No worries, happy simulating

Kind regards
