An AMR Capable Finite Element DiÆusion Solver for ALE Hydrocodes

چکیده
Abstract We present a novel method for the solution of the diÆusion equation on a composite AMR mesh. This approach is suitable for including diÆusion based physics modules to hydrocodes that support ALE and AMR capabilities. To illustrate, we proÆer our implementations of diÆusion based radiation transport and heat conduction in a hydrocode called ALE-AMR. Numerical experiments conducted with the diÆusion solver and associated physics packages yield 2nd order convergence in the L2 norm.

Implementation of AMR in Multi-Material ALE Hydrocodes
We present our recent work on interface reconstruction in a logically structured Lagrangian CFD code that now incorporates the MoF system developed by Shashkov’s group at LANS. We also discuss the models used to update and re-map the state variables in the mixed
متن کاملDynamic Fracture Analysis Using an Uncoupled Arbitrary Lagrangian Eulerian Finite Element Formulation
This paper deals with the implementation of an efficient Arbitrary Lagrangian Eulerian (ALE) formulation for the three dimensional finite element modeling of mode I self-similar dynamic fracture process. Contrary to the remeshing technique, the presented algorithm can continuously advance the crack with the one mesh topology. The uncoupled approach is employed to treat the equations. So, each t...

This paper introduces a computational strategy to collaboratively develop the Galerkin Finite Volume Method (GFVM) as one of the most straightforward and efficient explicit numerical methods to solve structural problems encountering material nonlinearity in a small limited area, while the remainder of the domain represents a linear elastic behavior. In this regard, the Element Free Galerkin met...
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...
متن کاملVolume-Filling Effects on Sloshing Frequency in Simplified and Explicit Dynamic Finite Element Models of Tank Wagons During Braking and Turning
Numerical analysis of fluid sloshing in tank wagons is amongst essential research ideas that are focused by railway engineers. The free surface of fluid becomes unstable and turns into a dynamic complex non-linear problem for fluid-structure interaction (FSI). In this paper, initially, the dynamic response of the tank, including lateral force analysis and pressure distribution during braking, i...
