Hi Felipe

>In fact, i was creating by pack cylinder but it seems like there is stress/overlap local even i didn't apply any force before. >That's why i try to find another method to do it without starting with tensioned/overlap.
 As I wrote, In randomDensePack always there would be initial overlap. Hence what you had found was correct. 
In some cases you can decrease intRadius, then no initial force will exist.

>it's really important the numbers of particles because i am wondering
if the best simulation will be creating either more >less 10000, 20000
or 50000 particles. is it possible to do it by using method 3?

It depends on your simulation. You can find a useful conversation in
where we talked about what are the essential parameters for calibrating
a sample and obtaining the same results with different geometry.
According to a review by [2] on YADE literature, the 10000 was
suggested.
