2.2.15.1 pair_style dem/lsd
Setup the discrete element method (DEM) linear dash-pot (lsd) pair style.
pair_style dem/lsd e rgcut pair_coeff i-type j-type kn Cn kt Ct e rcut
- temp: target temperature
- rgcut: global cut-off
- random-seed: seed for generating random number
- kn, Cn, kt, Ct, e, rcut: DEM force parameters
Examples:
pair_style dem/lsd 0.3 1.0 pair_coeff * * 1000 16.6016 314.29 6.3008 0.5 1
Description:
The force in the lsd DEM potential have spring and tangential forces along both normal and tangential
directions. The tangential force is under the Coulomb friction rule.
