The numerical simulation methods commonly used in the casting forming process are summarized. The main characteristics of the semi-solid alloy thixoforming are analyzed. It is concluded that the Lagrangian method of local mesh refinement is more suitable for the semi-solid state Numerical Simulation of Alloy Thixoforming Process. The algorithm is discussed and an example is given
