Abstract | In this paper we consider the numerical solution of the three-dimensional
(3D) fluid-structure interaction problem in haemodynamics, in the case of
physiological geometries and data, and finite elasticity vessel deformations.
We introduce new partitioned algorithms and compare their efficiency with
that of existing ones. We also study some new inexact variants, obtained
from semi-implicit approximations, and show that they allow to improve the
efficiency while preserving the accuracy of the related exact (implicit) scheme. |
