Dear Fluka experts,

Regarding my previous question on the "not complete" 3D data exporting

via usbrea, I thought to share with you an example to clarify my problem

in case that my previous question wasn't clear!

Attached, you will find a very simple FLUKA code (usbrea.inp) that

scours Edep in a small Cu cylinder, with binning: x and y = -2.5 to 2.5

(1 cm width, i.e. 5 bins for each axis) and z = 0 to 5 (1 cm width. So,

5 bins for this axis as well). The runs were merged in "usbrea_98.bnn"

via flair. $FLUPRO/flutil/usbrea has been used to produce and export the

formatted Edep data values in 3D matrix and saved in

"usbrea_3D_DataExport.txt". A 2D plot (in x-y plan) at fixed z=0 was

generated, and fluka saved the results automatically in

"usbrea_z0_98_plot.dat" file.

- The correct number of binnings is:

x-axis: -2.5, -1.5, -0.5, 0.5, 1.5, 2.5 (6 points)

y-axis: -2.5, -1.5, -0.5, 0.5, 1.5, 2.5 (6 points)

z-axis: 0, 1, 2, 3 ,4 ,5 (6 points)

Now,

1- usbrea_3D_DataExport.txt gives/export 125 Edep data points. These

come from 5 (x-bins) * 5 (y-bins) * 5 (z-bins).

2- usbrea_z0_98_plot.dat gives/exports 36 Edep data points. These come

from 6 (x-bins) * 6 (y-bins) * 1 (for the first z bin value, z=0).

The two export methods are not compatible! The 3D data export method via

usbrea gives less data points than it must? Why is that? Do I use usbrea

in a wrong way?

It is critical for me to understand the exporting method of usbrea,

because I further use the exported 3D data points from fluka as

input/initial values in other program.

I really hope to get some feedback from the fluka experts on this issue!

With my best regards,

Tamer
