This work presents recent advances in visualizing multi-physics, fluid-structure interaction (FSI) phenomena in cerebral aneurysms. Realistic FSI simulations produce very large and complex data sets, yielding the need for parallel data processing and visualization. Here we present our efforts to develop an interactive visualization tool which enables the visualization of such FSI simulation dat...

Systems involving flexible bodies interacting with surrounding fluid flow are commonplace, but are challenging to model numerically on account of their complex geometries and freely moving boundaries. In the present study, we developed an immersed boundary method (IB) for simulating fluid−flexible structure interactions. Our method is based on an efficient Navier-Stokes solver adopting the frac...

ABSTRACT This study evaluates the role of supercomputers in large-scale fluid/structure analyses of aerospace vehicles, with an emphasis on computational aeroelasticity dominated by complex fluid/structure interactions. The information presented is primarily based on responses to a web-based survey that was designed to capture the nuances of highperformance computational aeroelasticity and, in ...

Results of wellposedness and stability are presented for a partial differential equation (PDE) model which has been used to model certain biological and physical fluid-structure interactions. The coupling between the fluid and structural equations occurs across the boundary interface. A key feature in the analysis is the novel method of eliminating the associated pressure of the system. This is...

to the glass transition in dense colloidal dispersions using asymptotic expansions in the schematic F (γ̇) 12 model of mode coupling theory. The shear thinning of the viscosity in fluid states and the yielding of glassy states is discussed. At the transition between fluid and shear-molten glass, simple and generalized Herschel-Bulkley laws are derived with power law exponents that can be compute...

The simulation of multi-physics scenarios, in particular fluid-structure interaction has gained more and more importance in the last years due to increasing accuracy requirements for a large range of applications from biomedical fields to technical design problems. At the same time, this type of simulation has become feasible due to the increased computing power of modern supercomputers. Note t...

the structure of n,n'-bis(2-hydroxybenzylidene)-2,2-dimethyl-1,3-propanediamine, c19h22n2o2, has been studied at low temperature (120k) by means of single-crystal x-ray diffraction. solving the structure shows an orthorhombic unit cell, with p212121 space group, z = 4, a = 6.1046 (4) å, b = 15.8349 (11)å, c = 17.2898 (12) å and v = 1671.3 (2) å3. there are two relatively strong hydrogen bonds (...
