Thanks Bruno. (Sorry, I forgot to clicked Reply All the first time).   I'm using a relatively new version right before 'bex' is changed to 'fex'.  I have looped through in python:

for b in O.bodies:
    if b.shape.name == 'Sphere':
        if b.shape['radius']<0.0001:
             print b.shape[radius]

Since
nothing appears, all my radius are positive.  I've also checked the
smallest radii range at the start of the simulation before expansion. 
The radius of the smallest particles are between 0.005 and 0.006.  The
weird thing is that the step size at the start of the simulation is as
large as 200000.  I've included a screenshot
  

Yours,

Boon
