摘要：In this talk we will discuss a variant of phase-field modelling
derived from an energy variational formulation. Different models are derived and efficient numerical methods are proposed and analyzed. In particular, we discuss the algorithms based on spectral element method for the spatial discretization and stabilized ADI or auxiliary variable approach for the temporal discretization. Reduced order methods are then developed using by proper orthogonal decomposition and discrete empirical interpolation to improve the computational efficiency.
