Dear Mikhail,
 
Thanks !
 
I tried again in serveral combinitions and found that in USRBDX card, if the calculation type contains linE, namely: linE,linΩ or linE, logΩ, then it is a mandatory in case of isotope source.

      Dear all,

        

        As practice, I want to calculate the spectrum of Co60 source by
        using the USRBDX card and the fluence distribution by using
        USRBIN card in vaccum.

        

        I consult the manual to define the isotope source requested in
        BEAM card via SDUM=ISOTOPE and also with HI-PROPE, RADDECAY and
        DCYSCORE cards written in my input file.

        

        When running my input file, there is an error information dumped
        in log file:

        

        Program received signal SIGFPE: Floating-point exception -
        erroneous arithmetic operation.

        

        Backtrace for this error:

        #0 0x7F5E12939497

        #1 0x7F5E12939ADE

        #2 0x7F5E11E3E8EF

        #3 0x465D81 in master.0.usrbdx at usrbdx.f:937

        #4 0x456791 in newplo_ at newplo.f:34

        #5 0x409C57 in flukam_ at flukam.f:3176 (discriminator 8)

        #6 0x40791B in fluka at fluka.f:289

        #7 0x7F5E11E2AD64

        shall be addressed to the FLUKA Collaboration Committee, through
        fcc_at_fluka.org.

        Any permission may only be granted in writing.

        

        It seems that the error is due to USRBDX card and also there is
        nothing data generated by USRBIN card.

        

        I have attatched the input files in the attatchment.

        Could any one help me ? Thanks in advance !

        

        Best regards,

    Dear Zhefu Lee,

    

    Try to setup proper Emin and Emax values for USRBDX card. I suppose
    it is a mandatory in case of isotope source.

    

    *...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....

    USRBDX 1. PHOTON -22. TARGET
      VOID 1.usrbdx

    USRBDX 1.5E-3 100.E-6
      100. 1. &

    

    

    Best regards,

    Mikhail
