Key result
In 3D fluid-structure interaction simulations of prosthetic aortic valves, the Arbitrary Lagrangian-Eulerian technique was significantly limited by mesh deformation issues and failed at early opening, whereas the Immersed Boundary technique successfully completed the simulation.

Novel FSI valve models may refine fluid analysis; leaves open optimal discretization pending validation.
For 3D fluid-structure interaction simulations of prosthetic aortic valves, Eulerian-based approaches may be more practical than ALE-based methods due to mesh deformation limitations in the latter.
Bavo et al. (2016) studied Prosthetic aortic valve fluid-mechanics (computational simulation). Arbitrary Lagrangian-Eulerian (ALE) technique vs. Immersed Boundary (IB) technique was evaluated on Simulation performance and mesh deformation. In 3D fluid-structure interaction simulations of prosthetic aortic valves, the Arbitrary Lagrangian-Eulerian technique was significantly limited by mesh deformation issues and failed at early opening, whereas the Immersed Boundary technique successfully completed the simulation.
