Comparison of time semi-discretization approaches for DGM solution of linear elasticity problem

The goal of the presented paper is to compare the application of the STDGM to other time discretization schemes on several simple model problems. We present a comparison of the numerical methods based on the backward Euler ...

A posteriori error estimates of the discontinuous Galerkin method for parabolic problems

We deal with the heat equation discretized by discontinuous Galerkin finite element method in space and by backward Euler method in time. We present a simple and efficient a posteriori error estimate based on Helmh...

Numerical modelling of compressible flows in turbine cascades

Mathematical models for inviscid and also turbulent transonic flows through turbine cascades are presented. For numerical solution, finite volume upwind explicit (Runge-Kutta) and implicit (backward Euler) methods are consi...

An Implicit WLSQR Method for 3D Transonic Flows

This article deals with the extension of the high order finite volume weighted least-square (WLSQR) scheme into 3D. The high order WLSQR reconstruction is combined with the HLLC flux and the resulting semi-discrete system of equations is solved by th...
