Hi,
Are there any methon to generate a homogenous dense packing(porosity<0.4) in EDEM, when I use the "volume packing" in EDEM, the particles near the boundary were not as homogenous as particles in the center.
Thanks
Hi Raheem,
The Volume Packing algorithm takes geometry into account. If your boundary was a geometry that may result in a local reduction in the solid fraction due to the need to avoid particle-geometry overlaps.
Have you tried generating the packing in a domain with periodic boundaries only?
Best regards,
Stefan

Hi Stefan,
Yes, I tried generating packing with periodic boundaries, and I didn't find the selection in volume packing when I want to generate packing in normal distribution, can volume packing do this?
Regards!

EDEM still needs a geometry to create the particles in - in your case it should be a box with the same dimensions as the simulation domain and you should set the geometry type to be virtual. EDEM does not consider contacts between particles and a virtual geometry.
