Jérôme Duriez proposed the following answer:
Hi Weimin,

The doc of randomDensePack suggests you may only get uniform (in number)
size distribution with this function. So, it seems it does not suit your

You will thus need to generate your packing "manually", following the
classical procedure illustrated in examples/triax-tutorial/script-

- creation of a gas like ("cloud") initial packing with "makeCloud" function 
- isotropic compression of this packing until a solid state and a desired 
confining pressure

You will be able to specify a desired particle size distribution calling
"makeCloud" function, see its "psdSizes" and "psdCumm" attributes.
