Adaptive two‐step methods for semidiscretized wave equations

International Journal for Numerical Methods in Engineering, 1995
AbstractAdaptive two‐step direct integration methods are constructed for the integration of second‐order semidiscrete evolution equations possessing oscillatory solutions. The methods are based on a class of adaptive multistep methods for a semilinear test model whose frequency is known.

Semidiscrete pesticide transport modeling and application

Journal of Hydrology, 2004
A time-continuous and space-discrete method is proposed for three-phase (dissolved, adsorbed, and vapor phases) pesticide transport modeling in the vadose zone and a generalized semidiscrete solution is derived under conditions of heterogeneous media, unsteady flow fields, and space-time-dependent physical and biochemical processes concerning pesticide

Spatial Stabilization of Semidiscrete Elastodynamics

2008
Solutions of direct time integration schemes that converge in time to conventional semidiscrete formulations may be polluted at small time steps by noncausal oscillations. These pathologies are the deleterious effects of higher modes of spatially discrete formulations, which are approximated poorly.

A note on semidiscretization methods

Mathematics and Computers in Simulation, 1978
Abstract Discretization of the time variable by A-stable linear multistep methods in nonlinear evolution equations is considered. Stability and convergence results are presented, which can be applied to multistep-Galerkin procedures for nonlinear initial boundary value problems.

Convergence Estimates for Semidiscrete Parabolic Equation Approximations

SIAM Journal on Numerical Analysis, 1982
Semidiscrete methods for approximating the solutions of initial boundary value problems for parabolic equations are studied. The construction of these semidiscrete methods is based upon the availability of several different Galerkin type approximation methods for the associated elliptic steadystate problem.

Numerical integration of semidiscrete evolution systems

Computer Methods in Applied Mechanics and Engineering, 1981
Abstract Methods and algorithms for integrating initial value systems are examined. Of particular interest is efficient and accurate numerical integration of systems of ordinary differential equations that arise on semidiscrete spatial differencing or finite element projection for evolution problems characterized by partial differential equations ...

BV Solutions of the Semidiscrete Upwind Scheme

Archive for Rational Mechanics and Analysis, 2003
As strictly hyperbolic system of conservation laws of the form \[ u_{t}+f(u)_x =0 , \quad u(0,x)=\bar u (x) \] is considered, where \( u \in\mathbb{R}^N\), \(f:\mathbb{R}^N \rightarrow\mathbb{R}^N\) is smooth, especially from a numerical point of view, that means, a semidiscrete upwind scheme of this equation is investigated.
