A phase diagram was obtained for doublons with numerical simulations of the phase-field model. Numerical simulations of the phase-field model were performed in a channel to find the stable region. It was found that two seeds of the crystals with different sizes are initially set on the left side of the channel. The transition between the doublon and the dendrite was investigated by changing the anisotropy parameters stepwise and it was shown that the difference of the tip velocities of the doublon and the dendrite increases continuously from zero at a critical value of anisotropy.
