In this work, the recently presented model for the calculation of free surface dynamics of the melt in the induction crucible furnace in a simplified two-dimensional axisymmetric consideration is further verified. The developed model is applied to the case of electromagnetic levitation, and the very first results are presented. The two-dimensional model is generalized for three-dimensional consideration as well, and on the basis of the obtained calculation results the phenomenon of free surface wave propagation along the crucible wall is discussed.
