how to apply wall-fluid interactio​n coefficien​t epsilon in Lj

Hi Dears
I want to apply 2 type of atomic interaction in my simulation:
one type is liquid LJ with sigma and epsilon for fluid atoms
another type is wall-fluid LJ with epsilon(wf)=4*epsilon for interface of wall and fluid.
Is the following input script tru for this purpose???
#3d Lj simulation Box
dimension 3
boundary p s p
atom_style atomic
neighbor 0.3 bin
neigh_modify delay 5

create geometry

lattice fcc 0.81
region box block 0 14 0 12.8 -0.25 0.25
create_box 2 box
create_atoms 2 box
mass 1 1.0
mass 2 1.0

LJ potentials

pair_style lj/cut 2.2
pair_coeff * * 1.0 1.0 2.2
pair_coeff 1 2 4.0 1.0 2.2

I use Rc=2.2 and epsilon(wf)=4*epsilon
thanks
Elena

the easiest way to get an answer to this question
is to run the input and see if it runs correctly and
produces the correct output.
