Abstract

The Virtual Kinetics of Materials Laboratory : Dendritic Growth simulates the anisotropic solidification of a single seed with an N-fold axis of crystallographic symmetry. The competition between surface tension and heat transfer allows dendritic arms to grow. The user can control every aspect of the model such as the thermal diffusivity and the strength of the anisotropy. Default values are physical but arbitrary. This presented model is based on the phase field method (see cited literature below) and the example shown in the FiPy manual.
