Monolithic and Hybrid Approaches

Solvers for large-displacement fluid–structure interaction problems: segregated versus monolithic approaches

We compare the relative performance of monolithic and segregated (partitioned) solvers for largedisplacement fluid–structure interaction (FSI) problems within the framework of oomphlib, the object-oriented multi-physics finite-element library, available as open-source software at http://www.oomph-lib.org. Monolithic solvers are widely acknowledged to be more robust than their segregated counter...

A Note on Robust Preconditioners for Monolithic Fluid-structure Interaction Systems of Finite Element Equations

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 range of flows, e.g, water, blood, and air with highly varying density. Based on the complete LDU factorization of the coupled system matrix, the preconditioner is constructed in form of L̂D̂Û , where L̂, D̂ and Û are pr...

Discussion of Microkernel and Monolithic Kernel Approaches

The paper discusses monolithic approach against microkernel approach both used in operating systems. The paper presents the most critical features of operating systems concerning system architecture, communication model, and priority in processes, memory management and handling of any arrived exceptions as well as interrupts. The interrupt is a crucial factor for real time operating systems (RT...

Penalty-projection Method for a Monolithic Fluid Structure Interaction Solver

Abstract. In this paper we present the results of Fluid-Structure Interaction (FSI) computations of an incompressible solid object and laminar incompressible viscous flows using a combined penalty-projection algorithm. The system consists of a fluid region governed by Navier-Stokes equations and a solid domain described by elastic and hyperelastic structure mechanical equations. In particular w...
