KW - Fluid-structure interaction, viscoelastic fluid.
AB - <p style="text-align: justify;">We consider a fluid-structure interaction (FSI) problem that consists of a viscoelastic
fluid flow and a linear elastic structure. The system is formulated as (i) a monolithic problem,
where the matching conditions at the moving interface are satisfied implicitly, and (ii) a partitioned
problem, where the fluid and structure subproblems are coupled by Robin-type boundary
conditions along the interface. Numerical algorithms are designed based on the Arbitrary
Lagrangian-Eulerian (ALE) formulation for the time-dependent fluid domain. We perform numerical
experiments to compare monolithic and partitioned schemes and study the effect of stress
boundary conditions on the inflow portion of moving interface.</p>
