摘要：

A mesoscopic lattice Boltzmann model is proposed to investigate the dynamic evolution of solidstate structures during the hexagonal-to-orthorhombic transition, incorporating the micro-elastic theory. The model enables detailed observation of the morphology of both single- and multi- variant systems. The analytically recovered macroscopic governing equation is fully consistent with the kinetic theory, and the interactions between different domains are well characterized. The strategy opens up a vast range of solid-state phase transitions, particularly those involving multi-phase and multi-domain systems.
