Hi,
So I began testing out LAMMPS, but got an invalid fix style when i use
the command fix 1 wall freeze, i checked the src directory and noticed
that fix_freeze.h was missing, i downloaded a new tarball from here:
http://lammps.sandia.gov/download.html (first option), when I
extracted it again the file was still missing. Where am I supposed to
have downloaded the tarball from? or am i just doing something wrong
in my in file?

it is not missing. it is part of the granular package.
it is _very_ likely that you don't want to use fix freeze,
but either exclude the atoms that you don't want to move
from the time integration or set their velocities to 0.0
and use fix setforce. this has been discussed on the
list many, many times. search the archives.
axel.
Just a small addendum. The doc page for every command,
like fix freeze, will state if it is part of an optional package
that needs to be installed in order to use it.
