Hi guys,
As illustrated in attached figures, I always get the same curve when
running the simulation with the same packing (with either
neverErase=True or neverErase=False). I don't face the problem you
mentioned Robert...
I do have different curves for neverErase=True and neverErase=False
Random results (we are speaking of "yade -j1" right?) usually come from using
null pointers or uninitialized variables.
Running yade with valgrind (and debug symbols) would probably tell more.
In the case neverErase=true, I would double-check what happens if the
interaction becomes active again.
I am also curious as to why we see changes in these curves between
replicates (even for neverErase=False), despite our use of a constant
sphere packing...

packing) gives different behaviors
I ran your script multiple times but I am having trouble identifying the
different stress-strain behaviors you mention. What exactly is
different? Is it the post failure part of the curve (I
OK... We need neverErase=True for DFNFlow so what should we do? Create a
functor to erase the interactions?
