fix sph/density/corr command

Syntax:

fix ID group-ID sph/density/corr style args 

Examples:

fix corr all sph/density/corr shepard every 30

LIGGGHTS vs. LAMMPS Info:

This command is not available in LAMMPS.

Description:

In gerneral the pressure field in SPH exhibits large oscillations. One approach to overcome this problem is to perform a filter over the density.

The filterstyle shepard is one of the most simple and quick correction. Every nSteps timesteps the following rule is applied:
