Syntax:
pair_style smd/hertz scale_factor
Examples:
pair_style smd/hertz 1.0
pair_coeff 1 1
Description:
The smd/hertz style calculates contact forces between SPH particles belonging to different physical bodies.
The contact forces are calculated using a Hertz potential, which evaluates the overlap between two particles
(whose spatial extents are defined via its contact radius).
The effect is that a particles cannot penetrate into each other.
The parameter
The parameter scale_factor can be used to scale the particles' contact radii. This can be useful to control how close particles can approach each other. Usually, scale_factor =1.0.
Mixing, shift, table, tail correction, restart, rRESPA info:
No mixing is performed automatically. Currently, no part of USER-SMD supports restarting nor minimization. rRESPA does not apply to this pair style.
Restrictions:
This fix is part of the USER-SMD package. It is only enabled if LAMMPS was built with that package. See the Making LAMMPS section for more info.
