Abstract

Summary In this contribution, we present a phase-field model of advected meancurvature flow and of advected pattern formation in solidification. The model is based on the approach presented in [3], where an extensive literature list on methods treating mean-curvature problems can be found. The model represents a step towards simulation of solidification processes where the melt motion is important. We give a basic mathematical information concerning the weak solution of the model equations, introduce a numerical scheme based on the Finite-Difference Method, and show several numerical studies demostrating basic qualitative effects of advection in the given context.
