Note that the gaussian distribution will in average sample 50% of negative numbers which you then try to assign to the kinetic energy...

Subject: [fluka-discuss]: About user routine:how to define the energy distribution of part icles in source.f

Hi ,everyone !
Here is my question: I define the energy distribution of particles by sampling from a Gaussian distrbution,but there seems to be some error,who can help me find it?Thank you very much.





      REAL RGAUSS=0.0
      CALL FLNRRN (RGAUSS)
      ENSAMP=RGAUSS
      TKEFLK (NPFLKA) = ENSAMP
      PMOFLK (NPFLKA) = SQRT (ENSAMP * (ENSAMP + TWOTWO * AM(IJBEAM)))
