Abstract
A method of sensitivity analysis for determining acceptable ranges of uncertainty of tested model’s parameters was presented in this paper. Our approach is based on Morris method with modified sensitivity indicator. Solver from NuscaS system, which enables making simulation of casts solidification made from two-component alloys was used as a model. This model is built on the basis of the finite elements method, which is used to solve thermal conduction problem. Enthalpy formulation was used by the considered model. Acceptable ranges of parameters’ uncertainty are determined in the way that parameters’ values increases caused previously assumed changes of resulting quantity.
