A Splitting Moving Mesh Method for 3-D Quenching and Blow-Up Problems

We present a splitting moving mesh method for multi-dimensional reaction-diffusion problems with nonlinear forcing terms over rectangular domains. The structure of the adaptive algorithm is an elegant combination of an operator splitting and one-dimensional moving mesh. It is motivated by the nature of splitting method, which splits a multi-dimensional problems into a few one-dimensional proble...

Moving-Mesh Methods for One-Dimensional Hyperbolic Problems Using CLAWPACK

1. I N T R O D U C T I O N We study high-resolution finite-volume methods for the one-dimensional conservation law qt + f (q ) z = ~ (x ,q ) (1) on a moving grid, where the interface x~ between grid cells varies with time t~. Figure 1 shows a typical moving grid over one time step. We show how the wave-propagation algorithms developed in [1] and implemented in the CLAWPACK software [2] can be m...

A 3D adaptive mesh moving scheme

This paper presents an adaptive mesh moving technique for three-dimensional (3D) fluid flow problems that involve moving fluid boundaries and fluid–solid interfaces. Such mesh moving techniques are an essential ingredient of fluid–structure interaction methods that typically employ arbitrary Lagrangian– Eulerian (ALE) frameworks. In the ALE frame, the velocity field representing motion of the u...

A moving-mesh relaxation scheme for one-dimensional barotropic two-phase flow with cavitation

Cavitation is commonly defined as a phenomenon in a liquid-flowing system when the pressure of the liquid falls sufficiently low in some region of the flow so that vapor bubbles are formed. The study of the dynamics of cavitation is an active research in many fields of science and engineering. Typical examples in relation to various features and characteristics of cavitating flows can be found,...

Splitting Scheme for Poroelasticity and Thermoelasticity Problems

In this work, we consider the coupled systems of linear unsteady partial differential equations, which arise in the modeling of poroelasticity processes. Stability estimates of weighted difference schemes for the coupled system of equations are presented. Approximation in space is based on the finite element method. We construct splitting schemes and give some numerical comparisons for typical ...
