Joint Modeling of Wave Phenomena by Applying the Grid-Characteristic Method and the Discontinuous Galerkin Method

Abstract The aim of this work is to develop a hybrid computational method that combines the grid-characteristic on regular structured grids with discontinuous Galerkin unstructured tetrahedral grids. proposed makes it possible describe integration domains complex-shaped boundaries and contact calculate seismic fields taking into account topography Earth’s surface, while saving resources. This modification in three-dimensional case has been paper for first time. Examples using developed calculating elastic wave phenomena arising during prospecting are given. By way testing, comparison made results produced by curvilinear can be used not only prospecting, but also other objects complex shape.
