baloonworldMCNP is an incredidibly powerful, flexable monte carlo modeling program for determining the probablity distribution of nuclear events. My lecturers think that PTRAC is a command card in MCNP that saves the individual tracks taken by every single partical. What it actully does is produce a vast file filled with equal parts arbiatary digets and blank space. The seven tables in appendix I (and the referanceses in appendix E) may be consulted in an attempt to gleen some idea of what the numbers refer to.
PTRAC's creator writes:
"When I designed the ptrac format in the early 1990s the intention was that
it would be read by another program (Sabrina at the time), not by humans.
Reading through the files myself during development caused me at times to
want to go home and kick the dog. Had I anticipated the number of people
who would be reading the file over the years, the format might have been
different.
...
Should someone wish to implement something different, remember that the
first number in the ptrac file is a version number."
The first number in my PTRAC output files is -1. Which I assume means that considerable effort has been put in to making it worse.
