read data of nanofluid inside nanochannel

hi everyone
i simulate water-copper nanofluid and use the data file for initial geometry of molecules and atoms that visualizing by vmd…
i attached picture of it in # 1.
i don’t know where is my mistake beacause when i run my code with lammps the initial instruction fail and i visualize it too and attached in picture # 2.
can everyone give me some suggestions?
i modeled spc/e water molecules and use:
pair_style lj/charmm/coul/long

and

atom_style full
bond_style harmonic
angle_style charmm

there are no pictures attached, no error message, not enough of the
input to make any kind of productive statement.
