I would like to start running FSI simulations for cardiovascular applications. More precisely, I'm interested in the behaviour of aortic valve under physiological flow conditions in which the interaction of fluid and structure must taken into account and the valve undergoes very large deformations. I read that there are two approaches to couple fluid and solid solvers: segregated or monolithic. Apparently seregated solver has drawbacks in terms of accuracy and stability. Is any of the 2 coupling ways more advised for certain type of setups?
While searching online I have find several opensource codes such as Fenics, Oomphlib, ElmerFEM and LifeV (I have used LifeV in the past). Besides this, I have access to commercial software, but would like to have an open source alternative as well. This is for two reasons: self-education (I can look at the source code and learn more about the numerical method) and flexilibility - if I have some special requirement, I could eventually implement it.
Unfortunately I don't have the time to develop an FSI solver from scratch and I need to start running simulations fairly quickly before I dig into the source code. Which solver and method would you recommend so that the initial learning curve is not too steep?
