A conservative penalisation strategy for the semi-implicit time discretisation of the incompressible elastodynamics equation

Autor: Federica Caforio, Sébastien Imperiale

Publikováno v: Advanced Modeling and Simulation in Engineering Sciences, Vol 5, Iss 1, Pp 1-27 (2018)

Abstract The principal aim of this work is to provide an adapted numerical scheme for the approximation of elastic wave propagation in incompressible solids. We rely on high-order conforming finite element with mass lumping for space discretisation a

Correct conditions on the boundary separating subdomains

Autor: Yuri I. Skalko

Publikováno v: Компьютерные исследования и моделирование, Vol 6, Iss 3, Pp 347-356 (2014)

This paper presents definition and solution problem of correct conditions on the boundary, separating subdomains for hyperbolic linear equation systems. The solution algorithm is demonstrated by means of an example system of elastodynamic equations f

International audience; Discontinuous Galerkin (DG) methods are nowadays actively studied and increasingly exploited for the simulation of large-scale time-domain (i.e. unsteady) seismic wave propagation problems. Although theoretically applicable to

Mimetic operators are a kind of discrete operators which, on staggered grids, can accomplish "mimetic" properties analogous to their continuous counterparts. Furthermore, they can attain identical convergence order everywhere in the domain, including
