A monolithic unified approach for FSI and multi-fluid flow problems using the Particle Finite Element Method with fixed mesh
نویسندگان
چکیده
This paper describes a strategy to solve multifluid and Fluid Structure Interaction (FSI) problems using Lagrangian particles combined with a fixed Finite Element (FE) mesh . The method is an extension from the fluid-only PFEM-2 [14][15], which uses explicit integration over the streamlines to improve accuracy. As a result, the convective term does not appear in the set of equations solved in the fixed mesh. Enrichments in the pressure and field are used to improve the description of the interface between phases.

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...
متن کاملFully discrete error estimation for a quasi-Newtonian fluid-structure interaction problem
Fluid-structure interaction (FSI) problems have various applications in engineering and biology, where two dynamics, fluid flow and deformable structure, are considered in one system. Simulations of blood flow, tidal current turbines and gas explosions in pipelines are some well-known applications in this research area [2, 6, 9, 16, 20, 21]. FSI problems concern the mutual influence between two...
متن کاملFast Finite Element Method Using Multi-Step Mesh Process
This paper introduces a new method for accelerating current sluggish FEM and improving memory demand in FEM problems with high node resolution or bulky structures. Like most of the numerical methods, FEM results to a matrix equation which normally has huge dimension. Breaking the main matrix equation into several smaller size matrices, the solving procedure can be accelerated. For implementing ...
متن کاملA Monolithic Ale Newton-krylov Solver with Multigrid-richardson-schwarz Preconditioning for Incompressible Fluid Structure Interaction
In this paper we study a monolithic Newton-Krylov solver with exact Jacobian for the solution of incompressible FSI problems. A main focus of this work is on the use of geometric multigrid preconditioners with modified Richardson smoothers preconditioned by an additive Schwarz algorithm. The definition of the subdomains in the Schwarz smoother is driven by the natural splitting between fluid an...

Numerical modeling of machining processes is of significance in the parametric analysis and optimization of their performance. In this paper, a finite element-based model of abrasive waterjet (AWJ) cutting of a ductile material is presented with the help of an explicit, nonlinear finite element method. In this model, both solid-solid interaction and fluid-structure interaction are considered. T...
