内容摘要:

 In this talk we will discuss a variant of gradient flow models for multi-phase problem, including both time and space fractional phase-field models derived from an energy variational formulation. Through a number of examples, the model deduction and their numerical approximation will be discussed. The spatial discretization for the proposed models is based on the spectral element method whereas the temporal discretization makes use of a new class of schemes based on auxiliary variable approaches.
