To understand resulting effect of an electromagnetic stirring during solidification of alloy one should use either well-controlled experiments or numerical simulations. In the present work experiments on solidification of Al-7wt%Si alloy with RMF stirring performed in University of Miskolc are presented. Temperature data obtained during the experiments are used for simulations which are performed with a purely columnar solidification model. The numerical code developed in the SIMAP laboratory based on the ensemble averaged multiphase model with the envelope approximation is used for the simulations.
