A partitioned FSI simulation of a valve using Fictitious Domain and Augmented Lagrangian Methods

When tackling fluid-structure problems different approaches are available. 
Here we intend to focus mainly on the Fictitious Domain/Lagrange multiplier 
method as a way to approximate valve movement. 
And even though we are not yet able to address the arising problems in its full 
complexity we believe that direct simulation might help answer some questions. 
To this extend we developed a partitioned FSI algorithm that is able to handle 
the implementation of simple or complex structures without changing 
the solver and the coupling algorithm, thus keeping the fluid and structure codes independent. 
A qualitative comparison with a model found in the literature is shown 
as well as some simulations and recent results.
