Parallel processing for simulating 2D radial dambreak using FVM HLLE flux on OpenMP

Abstract

This paper presents the simulation of 2D dry-wet radial dambreak cases using shallow water equations on multicore processing. Here, OpenMP for parallel computing is used. The CPU time for parallel programming with N = 800 points is shown almost similar to the the CPU time for serial programming with N = 400. The speedup and efficiency using parallel with 16 processors are obtained 7.8 times for dry simulation, 8.6 times for wet simulation and 50% from the serial respectively. This means the computational cost using parallel reduces 50% from the average of computational cost by a single processor.
