چکیده
We present a technology of 3D seismic field simulation for high-performance computing systems with GPUs or Intel Xeon Phi coprocessors. This technology covers adaptation of a mathematical modeling method and development of a parallel algorithm. We describe the parallel realization designed for simulation based on using staggeredgrids and 3D domain decomposition method. We study the parallel algorithm behavior on computing devices: CPUs, GPUs, Xeon Phi coprocessors. We consider the results of experiments that were carried out on cluster NKS-30T of SSCC and cluster MVS-10P of JSCC for different tests for parallel algorithm.

Three Dimensional Numerical Simulation of Tsunami Generation and Propagation Due to Makran Subduction and run-up on Chabahar Bay and Makran Coasts
Makran subduction located at the northwest of the Indian Ocean nearby the southern coast of Iran and Pakistan. Makran subduction is the source of tsunamis that threaten southern coast of Iran. In this article, generation and propagation of 1945’s tsunami initiated by Makran subduction is simulated. For the three dimensional generation of the wave, advanced algorithm of Okada is adopted. The CFD...
متن کاملSimulation of Wave Propagation over Coastal Structures Using WCSPH Method
In this paper a space-averaged Navier–Stokes approach was deployed to simulate the wave propagation over coastal structures. The developed model is based on the smoothed particle hydrodynamic (SPH) method which is a pure Lagrangian approach and can handle large deformations of the free surface with high accuracy. In this study, the large eddy simulation (LES) turbulent model was coupled with th...

In this paper we have studied the effect of magneto-static field onpropagation of thermal wave generated in metal by pulsed laser. In fact this interactiongenerate acoustic wave in different mechanisms. However, always the commonmechanism in the interactions of laser pulse and metal is the thermo-elastic wavegeneration. Applying the suitable magneto-static field on the s...

متن کاملWave Propagation at an Interface of Elastic and Microstretch Thermoelastic Solids with Microtemperatures
In the present paper, the problem of reflection and transmission of waves at an interface of elastic and microstretch thermoelastic solids with microtemperatureshas been studied. The amplitude ratios of various reflected and transmitted waves are functions of angle of incidence and frequency of incident wave. The expressions of amplitude ratios have been computed numerically for a particular mo...
