Helle,

I am trying to 'compare' several runs made with different evolutions of parameters with time, wich implies the same 'initial' behavior ,
so according to https://yade-dem.org/doc/formulation.html?highlight=indeterminism#result-indeterminism using a single thread version of Yade would give the same results

so I have compiled with ENABLE_MPI=OFF and seed defined in the makeCloud  identical... BUT I got different results already just after the gravity deposition output after having launched twice the same py code though my batch command.

What I have missed to obtain my goal?

Luc
