摘要：Phase field model is a powerful and efficient mathematical tool to simulate the evolution of microstructures with complex morphologies. Despite of various applications on pattern formations and phase transitions, most efforts focus on the numerical methods for finding steady states. Here we introduce a novel concept of “solution landscape”, which is a pathway map consisting of all stationary points and their connections. We then present the solution landscapes of two phase field models, one is phase field model of confined diblock copolymer-homopolymer, and the other is nonlinear space-fractional phase field model.
