A new two-dimensional cellular automata and finite difference (CA-FD) model of dendritic growth was improved. which a perturbation function was introduced to control the growth of secondary and tertiary dendrite. the concentration of the solute was clearly defined as the liquid solute concentration and the solid-phase solute concentration in dendrite growth processes. and the eight mo... https://www.roneverhart.com/Cyspera-Pigment-Corrector-1-75oz-52ml/
