Solution of near-field underwater explosion (UNDEX) problems frequently require the modeling two-way coupled fluid-structure interaction (FSI). This paper describes addition an embedded boundary method to UNDEX framework for multiphase, compressible and inviscid fluid using combined algorithms Runge–Kutta, discontinuous-Galerkin, level-set direct ghost-fluid methods. A computational dynamics (C...

Reliability and security of power systems, especially in areas prone to earthquakes, depends on the seismic withstand its components interaction these with other elements. All relevant products should be designed tested guarantee high performance. Option which is strongly recommended for qualification shake table test. This way very expensive some cases like transformers impossible due weight s...

Study of wind farms is an area active research. Researchers have proposed simplified farm models that define the wake structure in a and how they affect performance turbines. Interestingly, these do not take into account important aspect fluid flow, i.e., fluid–structure interaction (FSI) between turbines wind, which has role to play. This motivated researchers implement numerical analysis tool...

We recently derived the unified continuum and variational multiscale formulation for fluid-structure interaction (FSI) using Gibbs free energy. Restricting our attention to vascular FSI, we now reduce this arbitrary Lagrangian-Eulerian (ALE) by adopting three assumptions wall. The resulting reduced achieves monolithic FSI coupling in Eulerian frame through a simple modification of fluid boundar...

In this article, we present a new unified finite element method (UFEM) for simulation of general Fluid-Structure interaction (FSI) which has the same generality and robustness as monolithic methods but is significantly more computationally efficient and easier to implement. Our proposed approach has similarities with classical immersed finite element methods (IFEMs), by approximating a single v...

In this paper we detail a fast, fully-coupled, partitioned fluid–structure interaction (FSI) scheme. For the incompressible fluid, new fractional-step algorithms are proposed which make possible the fully implicit, but matrixfree, parallel solution of the entire coupled fluid–solid system. These algorithms include artificial compressibility pressure-poisson solution in conjunction with upwind v...
