This study is part of a project to develop an integrated FEM system to study thermo-mechanical process of ingot and mold. Presented here is the development of a 3-D mathematical model and FEM system for the simulation of temperature fields and stress fields in ingot and mold during solidification of ingot . In addition, two example are given in this paper. From the results of those simulation, the following conclusions can be drawn: Thermal stress in mold during early stage of ingot solidification is an important contributor to the splitting of mold. In addition, coupling analysis and precise mathematical model of heat transfer at the mold-ingot interface are important to predicate gap formation time using FEM.
