Problem with diameter/radius when importing .geo

I created a circular group of particles in gengeo the important part of the code is:

pos=Vector3(0, 0, 0)
radio=5
rock=CircleVol(pos,radio)

packer3.generatePacking (
  volume=rock,
  ntable=mntable3,
  groupID=0,
  tag=2
)

Then I import the geometry into Esys and put a sphere with the code:

particle=NRotSphere(id=63000, posn=Vec3(0, 10, 0), radius=5, mass=1.0)
sim.createParticle(particle)

When I import the vtu results into paraview, the group of particles generated in gengeo has twice the size of the particle generated directly in the esys code (rock).

Also when I create a group of particles in gengeo and save results with mntable3.write(fileNameRoca+".vtu",2), the group looks full of particles, but after import it to esys and run simulation the diameter of the particles are smaller and the rock looks empty.

I made lots of test and I think that radius generated in gengeo are asumed as diameter in esys particle. Can somebody explain if I made something wrong or this is a bug of Esys.

I was not able to fing the version of the programes, but if you tell me how to I can post it.
