Karol Brzezinski proposed the following answer:
Hi,

your example still needs some patching before working at all ('damp' not defined etc.). However, the issue is that the facets have zero mass (any force divided by zero mass gives infinite acceleration). You try to prescribe some mass:
>mass = O.bodies[0].state.mass
but unfortunatelly O.bodies[0] is a wall that has no mass either.

Cheers,
Karol
