A bridging domain method for coupling continua with molecular dynamics
Shaoping Xiao,Ted Belytschko +1 more
TL;DR: In this article, a bridging domain method for coupling continuum models with molecular models is described, where the continuum and molecular domains are overlapped by bridging sub-domains, and the Hamiltonian is taken to be a linear combination of the continuous and molecular Hamiltonians.

Coupling of atomistic and continuum simulations using a bridging scale decomposition
Gregory J. Wagner,Wing Kam Liu +1 more
TL;DR: In this paper, the authors present a method for coupling molecular dynamics (MD) and continuum mechanics simulations that is based on the projection of the MD solution onto the coarse scale shape functions.

A monolithic approach to fluid–structure interaction using space–time finite elements
TL;DR: In this article, the authors present a simultaneous solution procedure for fluid-structure interaction problems, where the structural motion is described by geometrically nonlinear elastodynamics, and the fluid is modeled by the incompressible Navier-Stokes equations.

Curvilinear immersed boundary method for simulating fluid structure interaction with complex 3D rigid bodies
TL;DR: Numerical experiments for fluid structure interaction (FSI) problems involving complex 3D rigid bodies undergoing large structural displacements suggest that both the properties of the structure and local flow conditions can play an important role in determining the stability of the FSI algorithm.

A three-dimensional computational analysis of fluid-structure interaction in the aortic valve
TL;DR: Results show that during systole the leaflets of the stented valve appear to be moving with the fluid in an essentially kinematical process governed by the fluid motion.

Towards the ultimate conservative difference scheme V. A second-order sequel to Godunov's method
TL;DR: In this article, a second-order extension of the Lagrangean method is proposed to integrate the equations of ideal compressible flow, which is based on the integral conservation laws and is dissipative, so that it can be used across shocks.
