Hello. I am facing the following errors regarding the potential functions given below. I have also sent you the codes of my files. I would be grateful if you could guide me.
mass 1 12.01 # Tool Newton atoms (TN):C
mass 2 12.01 # Tool Boundary atoms (TB):C
mass 3 12.01 # Too Thermostat atoms (TT):C
mass 4 26.98 # Workpiece Newton atoms (WN):Al
mass 5 26.98 # Workpiece Boundary atoms (WB):Al
mass 6 26.98 # Workpiece Thermostat atoms (WT):Al
mass 7 65.38 # Zinc atoms (Zn) # Added for Zn

Please see Please Read This First: Guidelines and Suggestions for posting LAMMPS questions for how to correctly format quoted input and how to report issues in general (you don’t report your LAMMPS version and platform, for example). But the worst is that your quoted input is barely readable. Didn’t you notice that??

Your entire pair style set up is a mess.

This is obviously wrong. According to your mass commands, only atom types 4, 5, and 6 are Aluminium.

This section is complete garbage and not at all according to the documentation.
More importantly, it makes no sense to mix eam/alloy with meam. You should just use meam, but then again, your MEAM parameters are incomplete, too. How about this one?

Also, you are missing the carbon-carbon interactions (for which you could use Tersoff).
