You are going to need to provide parameters, at the very least charge and
VDW parameters for the iron, although more likely bond, angle and dihedral
parameters as well. You should do a thorough search of the literature to see
what people have done with iron atoms in classical MD simulations of the
system you are looking at. In addition see
http://www.rosswalker.co.uk/tutorials/amber_workshop/Tutorial_four_orig/
to get an idea of how to create your own atom types, add parameters etc.
All the best
Ross
