Calculation of elastic lattice Green's function in supercell

Dear Abiniters,

I want to get elastic static lattice tensorial Green's function in a large supercell (~1000 atoms, Gamma point only) to tie it with the continual limit in elasticity theory, so all I need is to get atoms displacements caused by unit point force separately acting in x-, y-, z-directions (produced by corresponding dispacement of one fixed atom).

I'm not familiar with response calculations, so I want to understand is there any sense to obtain such results using implemented response capabilities for statics?

Regards.
