Initial orientation distribution generated with Neper (left) and the orientation distribution after initial simulations with the orientation phase-field model (right). The orientation is given in radians. Because the orientation behaves as a phase-field, the grain boundaries in the coupled model are not restricted to follow the finite element grid and so there is no need to adapt the mesh to the morphology of the microstructure
