The interaction between the blood and the deformable artery leads to a very complex coupled problem
The solution of this fluid-structure interaction problem has been addressed by means of partitioned algorithms, whose convergence properties are in general very poor due to the high added mass effect characterizing the haemodynamic regime.
A theoretical analysis of the classical Dirichlet-Neumann scheme highlighted the instability of an explicit algorithm and the slowness of an implicit one. To improve the convergence rate Robin-type interface conditions have been studied. With a suitable choice of the interface parameters (based on the Optimized Schwarz Method), the convergence is quite independent of the added-mass effect
A different class of partitioned algorithms is derived by an algebraic fractional step method, leading to semi-implicit algorithms, where the geometrical problem is solved not exactly. In view of the applications to real clinical problems, semi-implicit algorithms have been extended to the case of non-linear models of elasticity for the vessel, obtaining efficient and accurate partitioned algorithms
A completely different approach consists in the monolithic schemes where suitable global preconditioners have been studied in view of an efficient parallel solution
We mention also the research on reduced models, where the structure is modelled as a membrane leading to simplified FSI problems involving only the fluid problem with suitable boundary conditions, and that on parameter estimation in FSI problems
