Dear all,
I am scouring energy using USRBIN card, according to the following steps (copied from 3D data file exported with usbrea):
Cartesian binning n. 1 "Edep_Core " , generalized particle n. 208
X coordinate: from -2.0000E+02 to 2.0000E+02 cm, 200 bins ( 2.0000E+00 cm wide)
Y coordinate: from -2.0000E+02 to 2.0000E+02 cm, 200 bins ( 2.0000E+00 cm wide)
Z coordinate: from 3.0000E+03 to 3.3200E+03 cm, 160 bins ( 2.0000E+00 cm wide)
Data follow in a matrix A(ix,iy,iz), format (1(5x,1p,10(1x,e11.4)))
I realized that for 3D data exporting via usbrea, I got 6,400,000 data points, which theoretically comes from 200*200*160 bins! However, this is not correct because from x (and y) coordinates that starts at x(y)= -200 to x(y)=200 (with 2 cm wide) I should have 201 bins not 200 bins! The same applies for the z coordinate I should have, for z=3000 to z=3320 (2 cm wide), 161 bins not 160. So, in total I should have 201*201*161= 6,504,561 data points!
Since the 2D data exportation (via 2D *plot.dat) is the only way that fuka exports "coordinates+data_values", I decided to use it to check its results! For a big surprise I found that at fixed z (e.g. z=3000) I got, from the *plot.dat file 40,401 data points for the same x(y) range, i.e. x(y)= -200 to x(y)= 200 (with 2 cm wide), which indicates that it follows the correct binning of 201*201 (not 200*200).
Why the 3D exportation produces less data points than the actual binning? Or I miss something here?
Regards,
Tamer
