Parameter-Free Time Adaptivity Based on Energy Evolution for the Cahn-Hilliard Equation

, 2016
It is known that large time-stepping method are useful for simulating phase field models. In this work, an adaptive time-stepping strategy is proposed based on numerical energy stability and equi-distribution principle. The main idea is to use the energy

General Uniqueness Results and Variation Speed for Blow‐Up Solutions of Elliptic Equations

, 2005
Let Ω be a smooth bounded domain in RN. We prove general uniqueness results for equations of the form − Δ u = au − b(x) f(u) in Ω, subject to u = ∞ on ∂ Ω.

Multi‐Bubble Solutions for Slightly Super‐Critical Elliptic Problems in Domains with Symmetries

, 2003
The aim of this paper is to show the existence of solutions with an arbitrarily large number of bubbles for the slightly super‐critical elliptic problem −Δu=u(N+2)/(N−2)+ε in Ω, subject to the conditions that u > 0 in Ω, and u = 0 on σΩ, where ε > 0 is a

Nonconforming Mixed Finite Element Method for Time-dependent Maxwell's Equations with ABC

, 2016
In this paper, a nonconforming mixed finite element method (FEM) is presented to approximate time-dependent Maxwell’s equations in a three-dimensional bounded domain with absorbing boundary conditions (ABC).

Internal monochromatic wave propagating over two bars

, 2015
Wave propagation in two-fluid system of different density is considered over two bars. The wave is monochromatic, and its dispersion relation is determined, for infinite depth of the upper fluid, which involves the physical quantities for each layers, i ...

A Monotone Finite Volume Scheme with Second Order Accuracy for Convection-Diffusion Equations on Deformed Meshes

, 2018
In this paper, we present a new monotone finite volume scheme for the steady state convection-diffusion equation. The discretization of diffusive flux [33] is utilised and a new corrected upwind scheme with second order accuracy for the discretization of
