A note on robust preconditioners for monolithic fluid-structure interaction systems of finite element equations
U. Langer, H. Yang
In this note, we consider preconditioned Krylov subspace methods for discrete fluid-structure interaction problems with a nonlinear hyperelastic material model and covering a large…
Open type quasi-Monte Carlo integration based on Halton sequences in weighted Sobolev spaces
Peter Hellekalek, Peter Kritzer, Friedrich Pillichshammer
In this paper, we study quasi-Monte Carlo (QMC) integration in weighted Sobolev spaces. In contrast to many previous results the QMC algorithms considered here are of open type, i.…
Numerical Simulation of Fluid-Structure Interaction Problems with Hyperelastic Models: A Monolithic Approach
Ulrich Langer, Huidong Yang
In this paper, we consider a monolithic approach to handle coupled fluid-structure interaction problems with different hyperelastic models in an all-at-once manner. We apply Newton…
Domain decomposition based parallel Howard's algorithm
Adriano Festa
The Classic Howard's algorithm, a technique of resolution for discrete Hamilton-Jacobi equations, is of large use in applications for its high efficiency and good performances. A s…
On the numerical stability of the least-squares method for the planar scattering by obstacles
Gilles Chardon
The scattering of waves by obstacles in a 2D setting is considered, in particular the computation of the scattered field via the collocation or the least-squares methods. In the ca…
