Seismic modeling is an integral part of the seismic data processing for oil and gas exploration, as it provides us the seismic response for a given earth model. Grid enabled seismic wave modeling can facilitate users in the area of geophysics to calculate synthetic seismograms using federated HPC resources and complex solution algorithms without knowing their complexities. The present paper is ...

Progress in MEMS and packaging design has made significant changes in the requirements for modeling tools. In order to design a modern microdevice or interconnect system it is no longer sufficient to limit the analysis to quasielectrostatic modeling due to smaller size and higher operation frequencies of the microdevices. On the other hand, a ‘full-wave’ analysis produces huge systems of equati...

The auxiliary differential equation finite-difference time-domain method for modeling electromagnetic wave propagation in dispersive nonlinear materials is applied to problems where the electric field is not constrained to a single vector component. A full-vector Maxwell's equations solution incorporating multiple-pole linear Lorentz, nonlinear Kerr, and nonlinear Raman polarizations is present...

Accurate modeling of seismic wave propagation in complex media is the key to many high end seismic processing algorithms. The performance is achieved by parallel implementation of algorithms on large compute clusters. This article describes the implementation of 3D acoustic and elastic wave propagation algorithms on a high performance computing system. A MPI (Massage Passing Interface) implemen...

Abstract: Elastic or acoustic wave-field modeling is an important part of seismic exploration. It can be used during the planning, processing and interpretation stages of seismic investigation. First attempts of using wave-field modeling were undertaken in the seventies by Alford, Kelly and others [1, 2]. These attempts were restricted by the limitations of computers at that time. Even now, com...

the main objective of this article is evaluation of the simplified models which have been developed for analysis and design of liquid storage tanks. the empirical formulas of these models for predicting maximum sloshing wave height (mswh) are obtained from mass spring models (msm). a finite element modeling (fem) tool is used for investigating the behavior the some selected liquid storage tanks...

I. INTRODUCTION THE accurate analysis, design and optimization of guided-wave structures are essential for the development of integrated photonic devices. Of all the methods used to simulate guided-wave propagation in these devices, the beam propagation method (BPM) has been one of the most popular approaches used in the modeling and simulation of electromagnetic wave
