After introducing the Discontinuous Galerkin (DG) method a detailed misfit analysis on its numerical approximation is performed. We investigate the accuracy of the scheme, the element type (tetrahedrons and hexahedrons), the spatial sampling of the computational domain and the number of propagated wavelengths. As the error norm we chose a time-frequency representation, which illustrates the tim...

This paper presents a numerical scheme of arbitrary order accuracy in both space and time, based on the high-order derivatives methodology, for transient acoustic simulations. The combines nodal discontinuous Galerkin method spatial discretization Taylor series integrator (TSI) time integration. main idea TSI is temporal expansion all unknown variables which are replaced by via Cauchy-Kovalewsk...

Abstract In this article, we briefly review the random choice method (RCM) and ADER methods for solving one two-dimensional hyperbolic conservation laws. The main advantage of RCM is that it computes discontinuities with infinite resolution. method, original problem reduced to a set local Riemann problems (RPs). exact solutions these RPs are used form solution problem. However, has following di...

We study in this paper three variants of the high-order Discontinuous Galerkin (DG) method with Runge-Kutta (RK) time integration for induction equation, analysing their ability to preserve divergence-free constraint magnetic field. To quantify divergence errors, we use a norm based on both surface term, measuring global and volume local errors. This leads us design new, arbitrary numerical sch...

In this paper, we demonstrate that the explicit ADER approach as it is used inter alia in Zanotti et al. (Comput Fluids 118:204–224, 2015) can be seen a special interpretation of deferred correction (DeC) method introduced Dutt (BIT Numer Math 40(2):241–266, 2000). By using fact, are able to embed theoretical background time integration schemes and prove relation between accuracy order number i...

1. Communication among cells, tissues and organ systems is essential for survival. Vertebrate and invertebrate animals rely primarily on three physiological systems for intra-organismal communication: the nervous, endocrine and immune systems. Rather than acting independently of one another, these systems communicate in an integrated fashion to coordinate suites of speciesappropriate physiologi...

We present a communicationand data-sensitive formulation of ADER-DG for hyperbolic differential equation systems. Sensitive here has multiple flavours: First, the formulation reduces the persistent memory footprint. This reduces pressure on the memory subsystem. Second, the formulation realises the underlying predictor-corrector scheme with single-touch semantics, i.e. each degree of freedom is...
