The detailed study of all the steps involved in the manufacturing of a casted part is of big practical relevance towards the optimization of both the part geometry and the production process so that manufacturing defects are minimized and a good performance of the part in its service life is ensured. This paper presents a summary of the research carried out by the authors in recent years on the development of finite elements models for analysis of casting processes. In the first part of the paper the finite element techniques derived for tracking the flow of the molten metal during mould filling are described. Then, the thermodynamical coupled formulation developed for modeling the evolution of the temperature and the strain/stress fields in both the casting and the mould during solidification and cooling is presented. The efficiency of the finite element models presented is shown in some examples of application.
