Dear experts,

I have installed the latest current version of FLUKA. I would like to study
optical photons and scintillation light following the example 12.2.4 of
the manual
concerning liquid Argon that I named optical.inp.

When I run it $FLUPRO/flutil/rfluka optical
I got a FLUKA abort
   *** The 4th field 0 of the following input card ***
  ASSIGNMAT 18.0 2.0 2.0
   *** does not contain a valid formatted fortran real number!!! ***
   *** It is ambiguous and it could be read differently on different
compilers ***
  *** depending whether it defaults or not to the blank=3D0 formatted
input rule ***

then I overwrite ASSIGNMAT 1.0 1.0 500. 1.0
   0.0
      with ASSIGNMAT 1.0 1.0 10.0
1.0 0.0

and the complain now is:

  Materials n. 18 (ARGON ) and n. 20(ARGON ) share the same name
in a (possibly) name based input
  Execution terminated.

My questions are the following:

1) Is any mistake somewhere? Can I run it as I did?

2) The routine Rfrndx of 12.2.2 is not in the uservax directory... so
shall I place it there and try
      to link it with the executable as we can do with the source.f? Is
it compulsory to use it?

3) Concerning physics... How I could simply count the number of produced
initial optical photons in the example and calculate the
fraction of them that hit one side of the rectangle box? Can this be
done with the USRBDX card and the normal FLUKA tools to read the
produced output file?

Thank you very much in advance

best regards

Georgios
