Hi Sergei,

This is because the simulation is dynamic AND you don't use collider's
Verlet distance.
In triaxial test (quasistatic), the collider run only each 100
itérations or even less, which makes its cost negligeable vs.
interaction dispatching.
Even in the dynamic case, you should use Verlet dist.
