Thanks Jan,

Yes my question was kind of 'useless'. What I am looking for is the
stress of each particle so I can map it against its position in 3D
space, to develop a 3d 'stress map' for various loads, ball size and
contact parameters. So it sounds like exactly what bodyStressTensors()
returns. But this function returns a tuple of length 1.

I have since found my answer, it turns out it is my amateur python
skills that let me down. The bodyStressTensors() module returns a tuple
of length 1, but that single entry is a list of the stress tensor for
each body (walls and facets included).

i.e.
stress=utils.bodyStressTensors()
stress=stress[0]

now 'stress' is a list of tensors (Matrix3) for each body.

I assume now I can loop through O.bodies and match the list index number
of 'stress' to body id numbers to map the stress to the bodies position
in 3D space.

Cheers
Alex
