What size growing scheme does YADE use in internalCompression?

Hi,
Yade does nothing internally on this aspect. You (if you decide to use
growParticles()[1]) can grow particles homogeously (i.e. independently of
the other particles). The method is illustrated in the tutorial script [2],
which in turns points to published papers [3,4,5,6].
I could list a lot more papers using this method (including independent
authors) but AFAIK [6] is the paper in which it is the most (though
quickly) described. The reviewer's question is ill-posed as far as I
understand it. You could ask him what he means by "validating". No serious
journal would publish the validation of such a thing, since it is obviously
valid.
It makes your problem very interesting from a socio-scientific point of
view: the reviewer is asking for a validation, but no reviewer would see
the validation of such a thing worth a paper.

Thank you Bruno !

That is a very detailed answer, totally convincing to reviewer‘s question.

In fact, the reviewer may be a experimental physicist, who do not know very specifics of how the simulation is elaborately installed.

His main doubt come from whether particles growing independently and uniformly, and whether specimens built by internally growing size resembles real mechanical system.

What I can only do is show him there are already a lot of papers there using this method.
