内容摘要:
In this talk, we propose and analyze the efficient decoupled methods to solve the large system arisen from a coupled model in free flow and porous media flow. Robin boundary conditions are applied to decouple the coupling conditions on the interface. Then, Robin-Robin domain decomposition method is established based on the two decoupled sub-problems. Moreover, optimized Schwarz method is used to derive the optimized Robin parameters which are able to improve the convergent behavior of the algorithms. Finally, the numerical experiments are presented to validate the accuracy and applicability of proposed algorithms.
