Ovito dislocation
WebIt only contains two crystals with an increasing mismatch along the X direction, as can be visualized with OVITO (here atoms are coloured according to the centrosymmetry parameter): This system is far from equilibrium, and only after a simulation will it relax into an edge dislocation. WebDec 1, 2024 · The software Open Visualization Tool (OVITO) is used to visualize the atomic configurations and perform dislocation quantifications [31]. 3.2. Tensile nanomechanics and deformation mechanism In OVITO, the Common Neighbor Analysis (CNA) method is applied to the atoms to mark their native crystal structure [32].
