The article presents the use of multiscale model to estimate the shape and size of the mixed and liquid zone in the modelling processes with semi-solid core. On a macro level to calculate the heat flow is used three-dimensional thermal model based on the Finite Element Method. While at the micro level it was used a Cellular Automaton (CA) combined with the finite element method based on the work of Gandin and Rappaz. Furthermore, the state of the cells influences to the temperature distribution it can be concluded that there is a bidirectional coupling. Each cell changes its state from liquid through mixed to the solid. Thanks to the use of cellular automata it can be possible both a better understanding of the process of creation and estimation the mixed and liquid zone. The paper presents the proof of concept of the original application allows to estimate and visualize the mixed and liquid zone.
