This paper introduces a novel method of modelling acoustic and elastic wave propagation in
inhomogeneous media with sharp variations of physical properties based on the recently …

This work is devoted to the modification of the grid-characteristic numerical method. We
propose using joint structured regular and curved computational grids to describe the …

In this chapter, a family of grid-characteristic methods for numerical simulation is considered.
These methods are developed and used to solve a wide range of applied problems …

In this paper, we describe the stages and results of investigating the features of oil-saturated
fractured zones through the analysis of the spatial dynamic wave patterns obtained by …

Gas emissions occur quite often in the North seas while carrying out oil-extracting works in
the area. It is very important to be able to forecast such gas accumulations spread for further …

Ultrasonic wave propagation in steel rails with explicit identification of flaws is numerically
simulated. The problem is to detect a vertical crack in a railhead by applying ultrasonic …

Fracturing is the fundamental quality of real rocks, their most important characteristic, the
subject of research and the source of information about the geological environment and oil …

Multiple waves arise in the process of shelf and land seismic prospecting as multiple
reflections of waves in the layers of water and sedimentary cover. Nowadays, multiple waves …

The goal of this study is to develop and apply a grid-characteristic numerical algorithm for
determining damage to an offshore object (ice island) by computing seismic wave …

In order to obtain an ultrasound image of the human head, it is necessary to solve the
corresponding inverse problem. In this case, acoustic approximation is usually considered in …
