Top: grain boundary energy as a function of misorientation for copper, obtained from atomistic calculations [50,51,52]. Bottom: result from calibration of model parameters for the orientation phase-field model (black stars) to fit the calculated grain boundary energy of a \(<100>\) tilt grain boundary from [50] (solid blue line). Only angles up to 30\(^\circ \) are considered in the calibration because the model does not capture the cusps seen in the full range of misorientation angles
