create more than one grain boundary

hi all,
I modeled a grain boundary in a fcc structure and got some results. but ńow i need to model at least two but can’t get a good structure so that the 2 GB intersect eachother.

thanks for any help or sugegstion

If you can't do it with the commands lattice
and create_atoms (within a region) and delete_atoms overlap
(to get rid of overlaps at the boundary), then you
will need to build the structure you want yourself and
put it in a data file for input to LAMMPS. Note
that you can use the lattice and create_atoms commands
as many times as you like to build complex geometries.
