Query: Computationally efficient phase-field models with interface kinetics   We present a new phase-field model of solidification which allows efficient
computations in the regime when interface kinetic effects dominate over
capillary effects. The asymptotic analysis required to relate the parameters in
the phase-field with those of the original sharp interface model is
straightforward, and the resultant phase-field model can be used for a wide
range of material parameters.
