Macrostructure

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.

Cost and Time Reduction

Save significant costs in materials and labor, in addition to reducing product development time.

Improve Quality and Precision

Prevent and correct casting defects, such as porosity, air inclusions, or solidification issues.

Process and Design Optimization

Experiment with different variables of the casting process to find the most efficient configuration.

Growth and Nucleation Model

Method based on the research "Application of cellular automata to model the microstructure of material during crystallization" by A. B. Belankov, V. Yu. Stolbov.
The cellular automata cells are grouped into blocks of the same size

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.
