Heat transfer in the domain of solidifying and cooling metal is accompanied by the process of mass diffusion. Connected with this phenomena changes of alloy component concentration are called the macrosegregation process. In the paper the sensitivity analysis is applied in order to find the mutual connections between the perturbations of partition coefficient value and the course of macrosegregation. On the stage of numerical computations the boundary element method has been used. In the final part of the paper the results obtained are shown.
