| Abstract: | The state-of-art of the simulation of directional solidification was given in order to describe its several methods,such as 3D dendrite envelope tracking,electromagnetic shaping and the phase-field method,etc;the phase-field method had been introduced mainly;additionally,the existing problems and the development directions in the future had been pointed out.Finally,the problems needed to be resolved urgently over the simulation of phase-field as well as the trends were proposed based on analyzing the disadvantages of the phase-field models available. |
