Nature of problem:
Dendritic growth in undercooled Al-3wt%Cu alloy melt under forced convection.
The lattice Boltzmann model solves the diffusion, convection, and heat transfer phenomena. The cellular automaton technique is deployed to track the solid/liquid interface.
Heat transfer is calculated uncoupled from the fluid flow. Thermal diffusivity is constant.
Novel technique, utilizing periodic duplication of a pre-grown "incubation" domain, is applied for the scale up test.
Running time varies from minutes to days depending on the domain size and a number of computational cores.
