Hi Wenxuan, You can use DEMdemo_BallDrop.cpp <https://github.com/projectchrono/DEM-Engine/blob/main/src/demo/DEMdemo_BallDrop.cpp> as an example and starting point. There, I created 11 templates with diameters ranging from 0.25cm to 0.35cm, then when instantiating particles, they randomly took one of the 11 templates. This is usually enough for emulating a size distribution.
However, if you want "truly random" distribution in the range of [8 mm, 12mm], then you probably just have to generate random floating numbers in this range, then create a sphere template based on this number, then create a particle using this template, then repeat the process. In the end, you will have as many templates as particles, and each of them is different. DEME should support this as well (and if it complains, please let me know). >From the simulation physics point of view, this is likely an overkill.
