Syntax:
pair_style smd/tri_surface scale_factor
Examples:
pair_style smd/tri_surface 1.0
pair_coeff 1 1
Description:
The smd/tri_surface style calculates contact forces between SPH particles and a rigid wall boundary defined via the smd/wall_surface fix.
The contact forces are calculated using a Hertz potential, which
evaluates the overlap between a particle (whose spatial extents are
defined via its contact radius) and the triangle. The effect is that
a particle cannot penetrate into the triangular surface. 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 the triangulated surface. 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 Build package doc page for more info.
