To achieve this the first order approximate evolution operator is considered. A recovery stage is carried out at each level to generate a piecewise polynomial approximation from the piecewise constants, to feed into the calculation of the fluxes. We estimate the truncation error and give numerical examples to demonstrate the higher order behaviour of the scheme for smooth solutions.enhttp://rightsstatements.org/vocab/InC/1.0/hyperbolic systemswave equationevolution Galerkin schemesrecovery stagefinite volumeMathematikThird order finite volume evolution Galerkin (FVEG) methods for two-dimensional wave equation systemWorking Paper2006-03-16urn:nbn:de:gbv:830-opus-189410.15480/882.128Hyperbolisches SystemGalerkin-MethodeEvolutionsoperatorWellengleichungInitial value problemsFinite difference methods11420/13010.15480/882.128930768290Other
