Abstract
Simulation codes currently used in the foundry industry are primarily used to predict casting quality, quality tied mainly to the location of defects such as shrinkage (voids of shrinkage origin). The effective use of the simulation system requires identification and knowledge of, adapted to the reality, physical parameters (thermal) of the casting - mould system. The lack of as complete as a possible identification of these values, used in modelling dependencies, is the cause of limitation of the development and scope of models describing casting solidification. The development condition of the simulation code in the foundry practice is the correct model installation and the use of the database corresponding to the model. The following application presents the analysis of the impact of simulation parameters on the prediction of the casting defects.
