[fluka-discuss]: DPA underestimation in Fe target

Dear fluka experts,

I am trying to reproduce the results from the paper in the attached file. This is a case of 1 GeV proton on 3 mm thick Fe with a beam area of 1 m^2. Table 2 in the paper shows the results of the DPA calculated by fluka, which is 0.28 for 1E20 beam particles.

My inputfile is in the attachment. USERBIN with region type was used for scoring. The output file print the following result:
accurate deposition along the tracks requested

According to my understanding, 4.2169E-22 * 1E20 = 4.2169E-2 should be the DPA. However, this value is one order of magnitude lower than the value 0.28 in the paper.

Could you please help to have a look if there is any misunderstanding of the output of fluka or there is any error in my inpufile?

Thanks a lot in advance.

Best wishes,
Xueyan Zhu
