A new three dimensional phase change/front tracking technique is described which combines the accuracy of an explicit Lagrangian front tracking of the phase interface with the ease of implementation of a simple level set/distance function technique. It fully models the important features of phase change dynamics: complex interface dynamics, fluid flow, heat and solute transport coupled with local interfacial physics involving surface tension, latent heat, interphase mass transfer and jumps in material properties. Three dimensional numerical investigations include the affect of fluid motion on solidifying dendrites and heat transfer during film and nucleate boiling.
