  • Method Details

    • position

      public static double position(double r, double size)
      Adjusts the postion of a particle assuming peridoic boundary conditions. The postion will be in the interval [0,size).
      Parameters:
      r - double
      size - double
      Returns:
      double

    • position

      public static int position(int r, int size)
      Adjusts the postion of a particle assuming peridoic boundary conditions. The postion will be in the interval [0,size).
      Parameters:
      r - int
      size - int
      Returns:
      int

    • separation

      public static double separation(double dr, double size)
      Computes the minimum separation using periodic boundary conditions.
      Parameters:
      dr - double the separation
      size - double the box size
      Returns:
      double

    • separation

      public static int separation(int dr, int size)
      Computes the minimum separation using periodic boundary conditions.
      Parameters:
      dr - int the separation
      size - int the box size
      Returns:
      int
