Abstract:

In this work use of the Morris method in sensitivity analysis of a numerical model of solidification is discussed. Sensitivity analysis permits to study influence of model parameters on the results, which makes it possible to determine which parameters have considerable influence and which are insignificant. The Morris method is suitable for analysis of computationally expensive models with great number of parameters, as it involves small number of model computations. Sensitivity of a numerical model of solidification developed by the authors is studied as a numerical example.
