Implicit finite element schemes for the stationary compressible Euler equations

International Journal for Numerical Methods in Fluids, 2011
SUMMARYA semi‐implicit finite element scheme and a Newton‐like solver are developed for the stationary compressible Euler equations. Since the Galerkin discretization of the inviscid fluxes is potentially oscillatory and unstable, the troublesome antidiffusive part is constrained within the framework of algebraic flux correction.

Asymptotic Error Expansions for Stiff Equations: The Implicit Euler Scheme

SIAM Journal on Numerical Analysis, 1990
This paper discusses the existence of an asymptotic expansion for the global error of the implicit Euler scheme applied to stiff nonlinear systems of ordinary differential equations. It is shown that in strongly stiff situations, a full asymptotic expansion exists at all gridpoints.

Multigrid solution of the Euler equations using implicit ENO schemes

28th Aerospace Sciences Meeting, 1990
In this paper, multigrid technique and implicit E N 0 scheme are combined to yield an efficient and accurate solution procedure for the calculation of steady-state solutions of the Euler equations. The recent developed essentially nonoscillatory schemes have some desirable properties, such as nonoscillatory and uniformly high order even a t critical ...

Semi-Implicit Euler-Maruyama Scheme for Stiff Stochastic Equations

1996
We discuss a semi-implicit time discretization scheme to approximate the solution of a kind of stiff stochastic differential equations. Roughly speaking, by stiffness for an SDE we mean that the drift coefficient of the considered equtaions satisfies the so-called one-side Lipschitz condition and the diffusion coefficients have the bounded derivatives.
