I want to create a layered wall ( like a wall in x,y plane having some
depth say 5 in the -ve z direction) which should contain two type of
atom. This wall should be a rough one that is the the two type of atom
should arrange in some way to make the wall. Then i want to put some
atom on some point say ( 1.5 0 2.5 ). There should be no interaction
between wall particles. There should be two different attraction
between atom to atom and wall particle to atom say one is lj/2.5 and
another is lj/5.0.
can anyone help me regarding this. Thanks in advance.

i don't see a lammps specific question here?
where exactly is your problem?
can anyone help me regarding this. Thanks in advance.
in other words: you are looking for somebody to do _your_ job.
so what kind of compensation are you going to offer for it?
Try implementing what you understood. If your implementations fail,
you should post your input and what you expect from the input (based
on LAMMPS documentation) and pose your questions. This may yield
better results on this list.
The fix wall commands in LAMMPS have an analytic formula
for how an idealized wall interacts with particles. What you
are describing sounds like you want a wall built of actual
particles in a particular arrangement. To do that you have
to build the wall yourself and input it in a data file, and just
freeze those particles so they act like a wall.
this is what I can offer:
