内容摘要:

In this talk, we discuss the parallel energy-stable solver for phase field models based on domain decomposition method. The phase field models are discretized by the discrete variational derivative method. After discretization, a semi-implicit system is obtained, which is unconditionally energy stable. We impose the Newton-Krylov-RAS algorithm for solving the discrete system. Several numerical simulations are finally reported to verify the model, scheme and the parallel efficiency.
