Question #211968 on Yade changed:

    Status: Open => Answered

Chareyre proposed the following answer:
Not sure it will work, but try:
s=bodyStressTensors()
vtkExporter.exportSpheres(what=[...,('particleStress','s[b.id]')])

Also note that bodyStressTensors() is doing a lot of computation, so it
is not appropriate to use it in your context, or to write something
like:

for b in bodies:
   bodyStressTensors()[b.id]

since it would recompute everything at each step in the loop. Better
compute it once and use the returned list, as suggested above.
