The methods of sensitivity analysis are applied in order to determine the influence of pouring temperature (the initial condition) on the course of casting solidification. In the first part of the paper the macro model of the process is considered, while in the second part the micro/macro approach is taken into account. On the stage of numerical simulation the finite difference method is used. In the final part of the paper the examples of computations are shown.
