Phase-field modeling of isotropic and anisotropic grain growth has been performed in 2D and 3D system. The multi order parameter grain growth model is adopted and OpenMP is implemented to enhance the computational efficiency. When the anisotropic grain growth phenomenon occurs, the misorientation distribution function of the low angle grain boundary is increased at the early stage and it converge to the certain value, 0.18 in 2D and 0.24 in 3D. The average numbers of faces of anisotropic grain growth is nearly same as the values of isotropic grain growth, which is 6.0 in 2D and 13.8 in 3D.
