Hi,
I'm trying to generate an assembly with PSD like Fig. 9 in [1] or Fig. 1 in [2]. Firstly, I set distributeMass = True, then, I pick up several point (xi,yi) from Fig. 9 in [1] or Fig. 1 in [2] and make psdSizes=[x1,x2,x3,x4],psdCumm=[0,y2,y3,1]. I am not sure if above mentioned way is correct, especially in terms of the following issues.

1. Should I set distributeMass = True or False.

2. In TriaxialStressController engine during triaxial test simulation[3], internalCompaction is set as True to reach confining pressure by growing particles. I wonder if all the particles are scaled up with the same scalar? Like the scale up in Fig. 1 in [2]?

3. By the way, I'm very curious about how it is achieved in Fig. 9 in [1], the numerical PSD is almostly agreed with experimental PSD, is there no particle growing during the isotropic compaction phase?

Thanks a lot.
Leonard
