Hello everyone,

I am trying to vary the ball according to slope height. The ball is distributed, but the space between them is created, as shown in the figure. Please tell me how to solve this issue.

The balls are generated entirely inside the box you specify, so it makes sense that there is a gap. You can solve this by specifying slightly overlapping boxes. e.g.

ball distribute box 0 465 0 50 0 50 radius 1 2.5 porosity 0.6;
ball distribute box 0 465 0 50 47 170 radius 0.001 2.5 porosity 0.5
ball distribute box 0 465 0 50 167 270 radius 0.0001 2.5 porosity 0.4
