Extd Defect DBᴼ

Note

  • This is an optional database.

Hardwired Aspects@

  • For simplicity all extended defects are considered to be regular geometric objects.
    • For the time-being, surface and line were the only geometric objects tested so far.
  • A line and surface are described by equation \(A_xx+A_yy+A_zz+D = 0\). Hence, are describe by 4D coordinates \((A_x, A_y, A_z, D)\).
  • If the extended defects are always considered as sinks. Hence, point defects captured by them are removed from the simulation.
  • Distance of a point defect from an extended defect is treated as an additional parameter, apart for it is regular parameters.
  • If there are more than one extended defects, distances from them are assigned to different parameters.
  • Shortest distance of a point defect from an extended object is calculated as described in here

Description@

  • # → Any thing above the hash symbol is considered as comments.
  • 0 → ID
  • 6 → Parameter ID of the defect to which the distanced is assigned a parameter value
  • surface → Type of extended defect
  • 0 0 1 0 → 4D coordinates, which are coefficients and constant in the equation \((A_xx+A_yy+A_zz+D = 0)\)
  • i → ignore (for future extensions)
