The submitted article deals with the study of casting and solidification of a 12 t ingot made of structural steel 42CrMo4 using numerical simulations in the THERCAST® and MAGMASOFT® software. The possibilities of each individual software in filling and solidification of steel were assessed, including the prediction of ingot defects such as porosity, shrinkage cavities or shrinkage porosities; the proportion of liquid phase, segregation of selected elements and solidification time were also monitored.. The results of the numerical simulations indicated that THERCAST® allows easier use of higher types of approximation of the function sought in order to increase the accuracy of the solution. If a part of the model needs to be defined more precisely, THERCAST® software can achieve this with local refinement, while places with simple geometry can be described using a coarser mesh. Unlike MAGMASOFT® in the basic version, THERCAST® has the possibility to simulate various behaviours of the material based on one geometric model, including, e.g., deformation, stress, density.
