Status: Open => Answered
Jan Stránský proposed the following answer:
Hello,
> if i run Two Times The same particles deposition with The same
material parameters
as explained above (in #1), with your usage of randomDensePack, you do NOT run
the same deposition, since the initial positions are different.
The same material parameters are necessary but not sufficient condition.
> when i put The positions in The script impact i obtain two results a
little bit different
see above, the final result of depositions are not the same, therefore
their usage in another simulation implies different results.
> And i wanted To know How can i avoid IT
as explained above (in #1), you can:
- avoid randomDensePack, loading the particles from pre-saved file
- use randomDensePack, but with memoizeDb argument
- use makeCloud instead of randomDensePack with constant nonzero seed argument
cheers
Jan
