Yufan Zhao is still having a problem:
Bruno, thank you very much.
But I don't know your meaning that there is no physical damping clearly.
"kinetic energy of particles needs to be dissipated since the energy
dissipation through friction damping during sliding may not be enough to obtain
numerical stability within a reasonable convergence time to quasi-steady state
.
Hence, a local non-viscous damping is added as a force term"----I saw similar
states in some paper that conducted simulation under the case of powder bed
additive manufacturing. And they set the damping coefficient as 0.75 but
without further explaination.
Maybe I didn't understand its meaning. Can you give some tips for it?
