question about lammps

hello

I’m material science engineering bachelor student and I work on simulation project with lammps. I have a question :
how can I create an alloy structure with lammps ? for example how can I create FCC lattice of Fe-30%Pt .
I read lammps manual and I try create it with set commend but unfortunately I can’t find useful way. I search sources too but all of them use a data file to create structure and they give no information about this excel file.
please show me an useful source I’m in very emergency situation for my Bs. project.

thank you for your consideration

the set command is one option. define a simulation cell with support
for two atom types, create an all Fe FCC lattice and then use set
type/fraction to change ~30% to Pt.

file to create structure and they give no information about this excel file.

what excel file are you talking about? LAMMPS neither reads nor writes
excel files.
