2D kMC screw dislocation

2D kinetic Monte Carlo simulation of screw dislocations in bcc metals 1. continuum theory is used to compute the elastic interaction energy 2. both periodic boundary conditions and non-periodic boundary conditions are used对体心立方金属中的螺旋位错进行二维动量蒙特卡洛模拟，采用连续介质理论计算弹性相互作用能量，同时运用周期性边界条件和非周期性边界条件。
