Jérôme Duriez proposed the following answer:
Hi,

"explosion" usually corresponds to the divergence of the Finite
Difference scheme used for integrating the motion equations (in
NewtonIntegrator engine), because of a too high time step.

Fortunately, Yade proposes the GlobalStiffnessTimeStepper [*] engine
exactly for this purpose: compute the appropriate (maximum) time step
that avoids divergence.

Unfortunately, it seems you're not using this engine in your script, but
a fixed time step instead (which thus may be too high).

Did you try with GlobalStiffnessTimeStepper (at best) / a lower time
step manually defined (at least) ?
