Schematic view of the simulation cell and core eigenstrain model. The cell contains a dipole of screw dislocations separated by a cut surface \({\bf{A}}\) shown in green and a Burgers vector \(1/2[\overline{111}]\). Atoms in different \((111)\) planes appear in different colors. The arrows show the edge displacements produced by the dislocation cores in the \((111)\) plane (magnified by a factor 50). These fields are modeled by representing the dislocation core as a cylindrical Eshelby inclusion schematically represented on the right-hand side
