jacopo is still having a problem:
Every time i want To test a soil i use The script that i posted before. When
The deposition ends i take The particles position And i copy them in another
script( The impact script, that i didn t post here) The problem Is: if i run
Two Times The same particles deposition with The same material parameters, when
i put The positions in The script impact i obtain two results a little bit
different, And i wanted To know How can i avoid IT

Jan Stránský proposed the following answer:
> I can t save The particles position And use IT for all The runs
Becouse when i change The material parameters The particles change their
interactions And have To do again the deposition
> but i m expected that repeating the test with the same value it will
return the same result.
sorry, I did not get this point..
If you want to get exactly the same results, you have to run the simulation
with the same parameters and also with exactly the same initial packing (i.e.
not using your current randomDensePack approach)
If you run different simulations ("Becouse when i change The material
parameters"), you get different results, no surprise..
