Hi,

i am trying to make a molecular dymamics simulation of granular matter using lamps but i have to type of particles and each one of them has different young modulus and Poisson ration, how can i make lammps to use diferentc parameter for this interacions

particle_type_1 <=> particle_type_1

particle_type_1 <=> particle_type_2

particle_type_2 <=> particle_type_2

Thanks, Miguel

particle_type_1 <=> particle_type_1

particle_type_1 <=> particle_type_2

particle_type_2 <=> particle_type_2

for more complex DEM models, please check out the LIGGGHTS package,

which is a derivative of LAMMPS with specific focus on supporting

granular media simulations.
