# gran surface sphere model

## Syntax

    surface sphere

## Description

This is the default surface model for a particle, it prepresents a smooth (non-rough) sphere. It is the default surface model for all LIGGGHTS(R)-PUBLIC simulations. In case of a multi-sphere simulation, this surface model is applied to all spheres within one rigid body.

Coarse-graining information:

Using `coarsegraining` in combination with this command should lead to statistically equivalent dynamics and system state.

Note

`Coarsegraining` may or may not be available in LIGGGHTS(R)-PUBLIC.
