Finite dissipation model of rapid solidification
The Phase-field model used in our study is based on the finite dissipation model developed by Steinbach et al. \cite{Zhang_2015,Steinbach_2012}. In this model, the rapid phase transformations are modeled using two concentrations fields which are linked by kinetic equation. The rate exchange between two phase is controlled using so called interface pemeability P.
