In this work, we consider the solution of fluid-structure interaction problems using a monolithic approach for the coupling between fluid and solid subproblems.  ...  Direct solvers tend to use too much memory even for a relatively small number of degrees of freedom, and, in addition, exhibit superlinear grow in arithmetic complexity.  ...  A comparison of various extension methods for fluid-structure interaction problems can be found in [76] .  ...
