Dear lammps-users,
I want to simulate the alloy of Zr (x)Cu( 90−x) Al( 10) with (x =10,15 20, 30)
How to change the concentration of these elements using LAMMPS

Can you help me please

In order to set the composition of an alloy, you create the corresponding number of atoms of each element. Atoms are created using either the read_data or create_atoms commands. If this still does not make sense, ask someone locally to explain it to you.
