    Dear Vasilis,

    I followed your way, and corrected the errors in my input file. But the
    problem still existed. My previous description was not clear. Let me
    describe the problem again.

     There are two homocentric balls made of water. One's radius is 5 cm, the
    other's is 10 cm. And the neutron source is put on the center and is
    isotropic. I can take data in 10cm boundary which is stored in
    "NeutronPropagation001_BoundaryNeu10", but can not in 5cm boundary which is
    stored in "NeutronPropagation001_BoundaryNeu5". Do you have data in the "
    NeutronPropagation001_BoundaryNeu5"? Thanks for your kind help.

    Best regards,
