I am simulating neutron propagation in a water ball and getting the
properties of neutrons across some boundaries. But I encountered some
problem when I used the subroutine bxdraw in mgdraw.f to get the
informations in boundaries. Let me describe the detail, 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, but can not in 5cm boundary. I don't know where I am
wrong ? Could anyone give me instrucions? Thanks very much!
Attached is my input file and mgdraw.f and source.f.
