The Macrostructure Solver allows you to model macrostructure formation in metallic alloys with body-centered or face-centered cubic lattices in the solid state. The software simulates heterogeneous grain nucleation both on the mold surface and within the molten metal.

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.
