        • Isotropic System (Commnet)
        • under shear flow
          
          At around gamma=1~2, the shear stress shows a peak, where the domain
          is elongated along (1,1,0)-direction. The 1st normal stress N_1
          gradually increases with the imposed strain, gamma. Then, N_1 reaches
          to a value at a steady state where the elongated domains are aligned
          to (1,0,0)-direction.
