Unconditionally stable algorithms for nonlinear heat conduction [PDF]

open access: yesComputer Methods in Applied Mechanics and Engineering, 1977
Abstract It is shown that many commonly used one-step algorithms which are unconditionally stable for linear transient heat conduction problems become conditionally stable in the nonlinear regime. Alternative algorithms are proposed which for linear problems are identical to those commonly used, whereas for nonlinear problems the unconditional ...

Low Mach Asymptotic Preserving Scheme for the Euler-Korteweg Model [PDF]

open access: yes, 2013
We present an all speed scheme for the Euler-Korteweg model. We study a semi-implicit time-discretisation which treats the terms, which are stiff for low Mach numbers, implicitly and thereby avoids a dependence of the timestep restriction on the Mach ...

One-Parameter Controlled Non-Dissipative Unconditionally Stable Explicit Structure-Dependent Integration Methods with No Overshoot

open access: yesApplied Sciences, 2021
Although many families of integration methods have been successfully developed with desired numerical properties, such as second order accuracy, unconditional stability and numerical dissipation, they are generally implicit methods.

High order unconditionally stable difference schemes for the Riesz space-fractional telegraph equation [PDF]

open access: yes, 2015
In this paper, a class of unconditionally stable difference schemes based on the Pad´e approximation is presented for the Riesz space-fractional telegraph equation. Firstly, we introduce a new variable to transform the original dfferential equation to an

Unconditionally stable schemes for equations of thin film epitaxy [PDF]

open access: yes, 2010
We present unconditionally stable and convergent numerical schemes for gradient flows with energy of the form √ (F(Δφ(x)) +ε2/2|Δ(x)|2) dx. the construction of the schemes involves an appropriate extension of Eyre\u27s idea of convex-concave ...

Constructing unconditionally time-stable numerical solutions for mixed parabolic problems [PDF]

open access: yes, 2007
This paper proposes a new numerical method based on an implicit difference scheme and the Fourier method which is applied to construct numerical solutions of mixed parabolic problems.
