Accurate, robust and efficient multiphysics-methods for the simulation of three-dimensional complex problems with immersed boundaries from engineering as well as biophysics are a highly interesting and challenging research area. Within this context, our motivation was to develop a general framework to solve a variety of multiphysics problem classes such as fluid-structure interaction (FSI) [1]-...

Designing large ultra-lightweight structures within a fluid flow, such as inflatable hangars in an atmospheric environment, requires an analysis of the naturally occurring fluid-structure interaction (FSI). To this end multidisciplinary simulation techniques may be used. The latter, though, have to be capable of dealing with complex shapes and large deformations as well as challenging phenomena...

Structure and fluid models need to be combined, or coupled, when problems of fluidstructure interaction (FSI) are addressed. We first present the basic knowledge required for building and then evaluating a simple coupling. The approach proposed is to consider a dedicated solver for each of the two physical systems involved. We illustrate this approach by examining the interaction between a gas ...

PURPOSE Image-based computational models with fluid-structure interaction (FSI) can be used to perform plaque mechanical analysis in intracranial artery stenosis. We described a process in FSI study applied to symptomatic severe intracranial (M1) stenosis before and after stenting. MATERIALS AND METHODS Reconstructed 3D angiography in STL format was transferred to Magics for smoothing of vess...

The use of lattice Boltzmann methods (LBM) for fluid flow and its coupling with finite element method (FEM) structural models for fluid-structure interaction (FSI) is investigated. A body of high performance LBM software that exploits graphic processing unit (GPU) and multiprocessor programming models is developed and validated against a set of twoand three-dimensional benchmark problems. Compu...

This paper presents a novel three-dimensional fluid–structure interaction (FSI) approach, where the meshless smoothed particle hydrodynamics (SPH) method is used to simulate motion of incompressible fluid flows, whilst structures are represented by simplified approach based on particle–spring systems. The proposed FSI technique allows use independent spatial–temporal resolutions for and structu...

In this study, aeroelastic response and performance analyses have been conducted for a 5MW-Class composite wind turbine blade model. Advanced coupled numerical method based on computational fluid dynamics (CFD) and computational flexible multi-body dynamics (CFMBD) has been developed in order to investigate aeroelastic responses and performance characteristics of the rotating composite blade. R...

In this article, we investigate the movement and vibrations of a blade due to presence mast. When passes in front mast, sudden pressure spike induces blade. To study influence stiffness, two different structures were studied. We present our numerical schemes concerning resolution flow, behavior structure coupling systems. Then, validate methods against an experiment (Bahaj et al., 2007). third ...
