Time accurate partitioned algorithms for the solution of fluid–structure interaction problems in haemodynamics

摘要: In this work we deal with the numerical solution of fluid-structure interaction problem arising in haemodynamic environment. particular, consider BDF and Newmark time discretization schemes, study different methods for treatment interface position, focusing on partitioned algorithms prescription continuity conditions at interface. We explicit implicit algorithms, new hybrid methods. numerically performances accuracy these highlighting best solutions applications. also their convergence properties respect to discretization, by introducing an analytical test case.
