Hello, I am trying to generate flux tally with the below code

\<?xml version="1.0"?\>

regular

50 1

\<lower\_left\>-70.71 -70.71\</lower\_left\>

70.71 70.71

1

1

flux

where 70.71 is the radius of my reactor. Now, In the tally.out file I got something

============================\> TALLY 1 \<============================

Mesh Index (1, 1)

Total Material

Flux 12.2047 +/- 6.30332E-02

Mesh Index (2, 1)

Total Material

Flux 11.7069 +/- 6.12077E-02

…

for the first two mash. And the rest is 0. I want to plot the neutron flux from center to radius of the reactor. I am not getting such values. Am I missing something? If I had the value I would use them to generate a downward plot in Microsoft excel. But, so far I am stuck on not getting the proper data in flux tally. Please help.
