In the paper the solidification model basing on the Mehl-Johnson-Avrami-Kolmogorov theory is discussed. In particular the sensitivity analysis of solidification process with respect to the mould parameters is presented. The method allows, among other things, to analyze the influence of the mould parameters on the temperature field in the system considered. The casting-mould domain is treated as a 2D one. On the stage of numerical computations the boundary element method is used. In the final part of the paper the example of computations is shown.
