Abstract | In this article we design new partitioned procedures for fluid-structure
interaction problems, based on Robin-type transmission conditions. The
choice of the coefficient in the Robin conditions is justified via simplified
models. The strategy is effective whenever an incompressible fluid interacts
with a relatively thin membrane, as in haemodynamics applications. We
analyze theoretically the new iterative procedures on a model problem,
which represents a simplified blood-vessel system. In particular, the Robin-
Neumann scheme exhibits enhanced convergence properties with respect to
the existing partitioned procedures. The theoretical results are checked
using numerical experimentation.
