In this paper, we discuss procedures for computing the mesh movement in staggered FSI-simulations. The mesh movement is divided into a global and a local level. The global level is based on the solution of an incremental linear-elastic solid model using the structure movement as Dirichlet boundary conditions, and error estimates to guide the node relocation in the interior of the uid domain. Th...

In this work, the robustness of the fluid-structure interaction simulation with a nearly incompressible elasticity model from our previous work [Partitioned solvers for the fluid-structure interaction problems with a nearly incompressible elasticity model, Comput Visual Sci, 14:227-247, 2012] is improved. At each time step of the FSI simulation, using properly chosen elementwise stabilization p...

In this communication, we show that the combination of 1 M lithium bis(trifluoromethylsulfonyl)amide and 1-butyl-1-methylpyrrolidinium bis(fluorosulfonyl)amide (LiTFSI/[Py1,4]FSI) can be regarded as a possible stable electrolyte for IL based lithium ion batteries. We compare the charge-discharge results with the electrolyte 1 M LiTFSI in 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl...

This paper presents a review on some developments of numerical methods for linear and nonlinear fluid-solid interaction (FSI) problems with their applications in engineering. The discussion covers the four types of numerical methods: (1) mixed finite element (FE)-substructure-subdomain model to deal with linear FSI in a finite domain, such as sloshing, acoustic-structure interactions, pressure ...

UNLABELLED The latest methods in estimating the probability (absolute risk) of osteoporotic fractures include several logistic regression models, based on qualitative risk factors plus bone mineral density (BMD), and the probability estimate of fracture in the future. The Slovak logistic regression model, in contrast to other models, is created from quantitative variables of the proximal femur ...

We consider in this paper numerical approximation of the linear fluid-structure interaction (FSI). We construct a new class of pressure-correction schemes for the linear FSI problem with a fixed interface, and prove rigorously that they are unconditionally stable. These schemes are computationally very efficient, as they lead to, at each time step, a coupled linear elliptic system for the veloc...

The recent TJLAB experimental data on inclusive electron scattering at high momentum transfer from complex nuclei are analyzed in terms of y scaling, taking into account the final state interaction (FSI) of the struck, off-shell nucleon. It is shown that at large negative values of y (x > 1), the Q2 dependence of the FSI is mostly driven by the elastic nucleon-nucleon cross section, and that, a...

With the diquark structure of Λc, we investigate the branching ratios of Λc → nπ and pπ. The results show that without considering the final state interaction (FSI), the branching ration of Λc → pπ is only of order 10−6 whereas taking into account the FSI effects, this ratio could reach 10−4 and is at the same order as Λc → nπ. Concrete values depend on phenomenological parameters adopted in th...
