Atomistic Dislocation Generation

Purpose

The Atomic Dislocation Generation routine is designed to create single dislocations in atomic systems such that their motion can be studied.

Capabilities

FCC, BCC, HCP, and Diamond materials

Edge dislocations in PAD and cylinder

Screw dislocations in cylinder

Edge dislocations in perfect crystal

Usage

First, you will need to compile the Fortran source code. Download the source file below and save it with a *.f90 extension. Then, compile it with either gfortran or ifort :

gfortran -O3 Dislocation.f90 -o atom-dislocation

or

ifort -O3 Dislocation.f90 -o atom-dislocation

Then simply run it. You may get a deallocation error, but check your directory because it may be fine.

 ./atom-dislocation 

It will prompt you for the relevant quantities:

• Crystal Structure
• Material or Lattice Parameter
• System Size (in units of the lattice vectors)
• Dislocation Type (Edge or Screw)
• System Geometry (PAD, Cylinder, or Infinite Crystal)
