Hello,
I work on nanoindentation with molecular dynamics (MD) and peridynamics (PD). I defined a sphere as a fictive indenter. For MD, when an atom enters in this fictive sphere, it´s automatically repelled more or less following K ( Indenter´s parameter) but for PD, as we theoretically work with small volumes which represent particles, a particle is repelled directly when it´s partially in this sphere, or center of small volume has to be in sphere to see particle be repelled ?

What is your question? If it’s about PD generally,
then the LAMMPS mail list is not a good place
to figure it out.

Actually, my question is How does fictive indenter work in peridynamics ? Because in MD we have atoms but in peridynamics, we have small volumes. And I know how indenter repels atoms but I don´t know how it repels small volume (particles).
Sorry for not being quite clear

The indenter knows nothing about peridynamics. It adds forces as specified to each point particle within the designated volume.
