Jan Stránský proposed the following answer:
Hello,
please provide your code and how you run yade.
Basically:
- if you run Yade in parallel (using -j N option), it is expected behavior [1]
- if your computation/export depends on real time (e.g. realPeriod in PyRunner), you cannot expect exactly same results
cheers
