Creating hollow hemisphere by using region lammps

Dear all,

I can use region to create a spherical structure, but I don’t know how to use lammps region command to create a hemisphere or a hollow hemisphere (like this : http://lammps.sandia.gov/pictures.html#nanotip ).

Any suggestions?

Best Wishes!

You can build complex regions through forming intersections and unions of the region primitives.
