The Macrostructure Solver allows for modeling the formation of the macrostructure of metallic alloys that have a body-centered cubic or face-centered cubic lattice in the solid state.
Model of heterogeneous nucleation of grains both on the surface of the mold and in the volume of the molten metal
Columnar-to-equiaxedtransition
Competitive growth of grains
Prediction of stray crystals in single-crystal parts
Directional solidification
Single сrystal сasting
Save significant costs in materials and labor, in addition to reducing product development time.
Prevent and correct casting defects, such as porosity, air inclusions, or solidification issues.
Experiment with different variables of the casting process to find the most efficient configuration.
The method includes the calculation of temperature fields using the Fourier module on a finite element mesh.
The cellular automata cells are grouped into blocks of the same size, which depend on the temperature gradient in the casting section. The model takes into account the nucleation and growth of grains in the two-phase zone of the casting, which changes over time. The activation or exclusion of blocks from the calculation process is performed as needed.
The growth of the grains is modeled using the rules of the cellular automaton, ensuring a consistent growth of the grain from a smaller to a larger scale.
