Hello,

Please try to make the codes MWE [3], W = working. Here:

correctly？
see above, just modify your script

the modification seems ok, IMO it is the easiest approach.
It should work for "bouncing" = interactions without significant
sliding/rotation.
It would behave strangely for "long sliding" or "largely rotating"
interactions. The equivalent radii, area and refLength are set at the
interaction creation time and kept constant for the interaction lifetime. If
the situation changes significantly (sliding, rotating,...), this easy "hack"
should be replaced by a more robust approach.
Just curious, are the two if branches (poly-poly and poly-sphere)
different from each other and/or different from the sphere-sphere
contact?
Cheers
Jan
