MCNPX do not finish a simulation possible bug in the code

  1. Aug 11, 2016 #1
    I am testing the MCNPX plugging MCUNED to make calculations with neutron generators. After the compilation many examples to test the installation are provided. But one of them (I attached the code below) starts but it never finish. Just keeps in the first rendezvous. I first though in a problem in the compilation to do parallel calculations, but I realized that I had the same problem when I tried to run the input in serial or with MCNP6 or MCNPX without MCUNED. Any idea where the problem may be? I also tried reducing the initial number of particles (from 1E5 to 10) to see if was only a matter of time. But it keeps always at the first rendezvous. The programm is perfectly running with other imputs (for example the same one give it below but changing the par=a to par=h)

    The code is the following.

    test light ion table: a on Cu63
    1 1 -8.94 -1 imp:n,p,h,d,t,s,a=1
    2 0 1 imp:n,p,h,d,t,s,a=0
