Hi, Just to give some figures about this bug: Random examples of triaxial simulations (with 20000 spherical particles and 6 boxes) show here ~ 45% of sphere-wall interactions that are useless at the end of the simulation. Ie ~ 3% of the (real) interactions total number.
I think checking for penetrationDepth < 0 around l.95 of the code [1], before deciding to "continue", would make sense and solve this bug. OK ? Do we take the opportunity to replace the shape test [2] with something else ?

And the user ends up with much more interactions than necessary.. I'm filling a Bug report for the record and possible discussion about desired behaviour (sorry I could not provide a MWE !)
