Random distribution of non-uniform size spheres in a Box
 

Hey folks,

I am looking for ideas of how to build a stack of randomly distributed non-uniform size spheres in a box (Geometry). This is more close to a packed bed geometry. The main objective of the model is to study the heat and mass flow profile over each spheres. I am trying to find which tool should i use for building the geometry. Once the geometry is ready, doing a CFD analysis should not be an issue.

Thanks,
