Fluid-structure interactions (FSI), i.e., the interplay of some moveable or deformable structure with an internal or surrounding fluid, are among the most widespread and most challenging coupled or multi-physics problems. Although much has been accomplished in developing good computational FSI methods and despite convincing solutions to a number of classes of problems including those presented in this book, there is a need for more comprehensive studies showing that the computational methods proposed are reliable, robust, and efficient beyond the classes of problems they have successfully been applied to.This volume of LNCSE, a sequel to vol. 53, which contained, among others, the first numerical benchmark for FSI problems and has received considerable attention since then, presents a collection of papers from the "First International Workshop on Computational Engineering - special focus FSI," held in Herrsching in October 2009 and organized by three DFG-funded consortia. The papers address all relevant aspects of FSI simulation and discuss FSI from the mathematical, informatical, and engineering perspective.

If unaddressed, end-stage renal disease (ESRD) can result in impaired renal function, development of cardiovascular diseases, and death. Although effective, dialysis conducted via arteriovenous fistulas (AVF) has been linked to the development of pulmonary hypertension (PH). The objective of this work was to use magnetic resonance imaging (MRI) and computational fluid dynamics (CFD) to model pulmonary artery (PA) blood flow and PA fluid-structure interactions so properties of these models could be related to clinical parameters relevant to PH and ESRD. Due to the global pandemic, one (n =1) adult ESRD patient underwent cardiac MRI for PA reconstruction. Short-axis cine scans and phase-contrast scans were used respectively to recreate the patient's PA geometry in Mimics 20.0, an imaging segmentation software, and derive a patient-specific velocity waveform of blood flow at the PA inlet. Computational fluid dynamics (CFD) and finite element models of vessel deformation were created in ANSYS Workbench 19.1. Steady-state models (CFD, linear elastic fluid-structure interaction (FSI), and hyperelastic FSI) were run using a constant inlet velocity and, where applicable, mechanical properties for vessel walls taken from literature. Transient models (CFD and linear elastic FSI) were also created to simulate pulsatile blood flow and, where applicable, the interaction with the artery wall. Moderate differences were observed among the various steady-state models, whereas only minimal differences were found between transient models. These differences may be due to limited mesh resolution, which was later identified in a mesh sensitivity analysis. Although only minor differences were found between fluid results for the transient CFD and FSI model, the computational cost of the FSI model was much greater. FSI models of PA hemodynamics may not offer different results for hemodynamic properties, but they may be used in future studies when arterial remodeling and cellular stress and strain distributions are of interest. This study offered insight into computational modeling of PA blood flow and may be used as reference for future studies seeking to apply this methodology to a larger patient population. Eventually, this type of modeling may be used to identify metrics of interest that physicians can use to more closely monitor AVF development during hemodialysis.

This book starts by introducing the fundamental concepts of mathematical continuum mechanics for fluids and solids and their coupling. Special attention is given to the derivation of variational formulations for the subproblems describing fluid- and solid-mechanics as well as the coupled fluid-structure interaction problem. Two monolithic formulations for fluid-structure interactions are described in detail: the well-established ALE formulation and the modern Fully Eulerian formulation, which can effectively deal with problems featuring large deformation and contact. Further, the book provides details on state-of-the-art discretization schemes for fluid- and solid-mechanics and considers the special needs of coupled problems with interface-tracking and interface-capturing techniques. Lastly, advanced topics like goal-oriented error estimation, multigrid solution and gradient-based optimization schemes are discussed in the context of fluid-structure interaction problems.

Understanding fluid and structure interactions in biological airways is essential for explaining the physics of gas exchange that governs air flow in human and animal lungs. However, a limited number of studies are available due to the challenges of modeling and lack of experimental data. This study bridges the knowledge gap through Fluid-Structure Interaction (FSI) simulations combined with mechanical tissue testing. FSI is a coupling between two classic simulation methods: Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA). FSI is especially popular among researchers performing biomedical and biomechanical studies, due to the complex, dynamic geometries. In the case of human lungs, the geometry of respiratory tract is extremely complex. To accurately model the behavior of the lower respiratory tract, smaller portions of the respiratory system: the trachea and two generations of connecting bronchi (part of the upper airway) were specially chosen for this research. Couple case studies have been used to prove the validity of the human lung FSI simulation results. The case studies included a quasi-2D "square balloon" FSI simulation and a 3D balloon FSI simulation. In addition, tensile tests were conducted to obtain material properties of porcine tissue for the lung FSI simulation. Material properties were determined with curve fitting of porcine tissue in axial and circumferential directions to further enhance the accuracy of the human lung FSI model. Conclusions from each case study, experimental testing, and human lung FSI are provided and serve to advance the interdisciplinary study of respiration kinetics.

An automated Fluid-Structure Interaction (FSI) analysis procedure has been developed at ATK Thiokol Propulsion that couples computational fluid dynamics (CFD) and structural finite element (FE) analysis to solve FSI problems. The procedure externally couples a steady-state CFD analysis using Fluent(R) and a structural FE analysis using ABAQUS(R). Pressure results from the CFD solution are interpolated and applied as pressure boundary conditions on the structural FE model. Displacements from the structural analysis are interpolated and applied to the boundary of the CFD mesh. Iteration between the CFD and the structural analysis continues until a solution is reached. The FSI procedure provides controls to monitor the solution and define termination criteria, as well as manage output. Automatic report generation of the solution is another feature of the FSI procedure. Plans and funding are in place to extend the FSI procedure to include coupling with thermal analysis as well. The FEM Builder(copyright) program provides pre- and post-processing functions for the FSI procedure, such as geometry creation, finite element mesh generation, material property definition, and boundary condition application. Several of the pre-processing functions were created exclusively for FSI solutions. The FEM Builder(copyright) program provides interfaces to other finite element pre/postprocessors and a number of analysis programs. Scripted access to FEM Builder(copyright) program functions is provided through the FEM Python module. The FEM Python module functions provide the basis of the FSI procedure. The FEM Builder(copyright) FSI procedure is applied to the analysis of a fictitious solid rocket motor. The problem of bore choking is examined in order to demonstrate the capabilities of the FSI procedure on a problem with potentially large structural deformations. An overview of the input required by the FSI procedure to solve this problem is discussed.

Fluid-structure interaction (FSI) effects often must be considered when flexible structures are subjected to unsteady flows. Large-scale unsteady flows may excite structural vibrations significantly and cause the fluid flow to be altered by the large amplitude vibrations. In this research, a partitioned FSI modeling approach is employed to simulate such large amplitude structural vibrations interacting withturbulent flows. The partitioned approach is based on the fixed-point iteration scheme that tightly couples the in-house finite-element structural code FEANLand the open-source computational-fluid dynamics (CFD) library package Open-FOAM. For turbulent ow predictions, hybrid turbulence models such as Delayed Detached-Eddy-Simulation (DDES) and k.
