✦ Synopsis

In this paper, an a posteriori error estimation technique for hyperbolic conservation laws is proposed. The error distributions are obtained by solving a system of equations for the errors which are derived from the linearized hyperbolic conservation laws. The error source term is estimated using the modi®ed equation analysis. Numerical tests for one-dimensional linear and non-linear scalar equations and systems of equations are presented. The results demonstrate that the error estimation technique can correctly predict the location and magnitude of the errors. In addition, it is shown in an example that the estimated error source terms can be used for grid adaptation to control the magnitude of error.

We analyze the discontinuous finite element errors associated with p-degree solutions for two-dimensional first-order hyperbolic problems.

An upwind, finite volume method is proposed for the direct solution of one-dimensional, hyperbolic systems-based sensitivity equations. Sensitivity equations for hyperbolic systems of conservation laws require a specific treatment of discontinuities, across which Dirac source terms appear, thus lead

Methods for a posteriori error estimation for finite element solutions are well established and widely used in engineering practice for linear boundary value problems. In contrast here we are concerned with finite elasticity and error estimation and adaptivity in this context. In the paper a brief o
