particledynamicsstuff Module Reference

## Public Member Functions

subroutine particleparticlecontact (dt, Coord, Coord2, Velo, Velo2, Force, Force2, Contact)

subroutine particleparticlecollision (dt, Coord, Coord2, Velo, Velo2, Force, Force2, Collision)

subroutine particlewallproc (No, Rinit, Rfin, Vinit, Vfin, Lambda, FaceIndex, ParticleStatus)

## Detailed Description

The particle-particle and particle-wall interaction for particle dynamics These are placed in a module since a private subroutine may not be passed as a parameter.

## Member Function/Subroutine Documentation

 subroutine particledynamicsstuff::particleparticlecollision ( real(kind=dp) dt, real(kind=dp), dimension(3) Coord, real(kind=dp), dimension(3) Coord2, real(kind=dp), dimension(3) Velo, real(kind=dp), dimension(3) Velo2, real(kind=dp), dimension(3) Force, real(kind=dp), dimension(3) Force2, logical Collision )

Subroutine for getting particle-particle interaction The subroutine may return the new positions and new coordinates, or alternatively the initial coordinates are tampered so that with standard time-integration the final position will be the same.
