construction of three dimensional FCC grain structure

Dear all,

I am new to lammps and MD calculations.
I want to simulate the mechanical properties of three dimensional
grain structure of FCC metals. Is there a command or code to generate
such structure? Appreciate any suggestion and comment!

Happy new year..

Thanks

Dear Lin

yes, please see the lattice command.
