Hi,
I am looking to generate random ellipsoids in a cube, given the volume fraction of ellipsoids (say 40%), non-overlapping (can touch), and they must follow certain particle size distribution. One instance could be, 60% of 2mm, 20% of 4 mm, 15% of 8 mm and 5% of size 16 mm. These sizes (2mm, 4 mm...) are the lengths of the largest semi-principal axes.
Thank you.
