| Abstract: | Directional solidification and single crystal will be the development direction of the casting microstructure simulation. First, the basis thought of microstructure simulation has been brief introduced; and then introduced the 3D dendrite envelop tracking simulation, this method is for simulating casting of unidirectional solidification which is sensitivity to vice. At the same time the result of 2D simulation with Dendrite Envelope Tracking Method has been presented. |
