“…While atomistic models are needed to provide accurate descriptions of defects they are usually too expensive computationally to allow sufficiently large-scale simulations that resolve the elastic far-field, which can, instead, be modelled efficiently by a coarse-grained continuum model. Methodologies for coupling the two different material descriptions were first described in [16,15,24,31]; more recent examples are [1,11,32,14,28]. The numerical analysis of atomistic/continuum hybrid methods is a topic of active research [4, 5, 8, 9, 11, 12, 17-19, 23, 25, 26].…”
