This article proposes a novel graphics processing unit-based active nematic flow solver based on the smoothed particle hydrodynamics (SPH) method. Nematohydrodynamics equations are discretized using SPH algorithm. Flow behavior, ordering, topological defects, and vorticity correlation calculated discussed in detail. The spectrum of kinetic energy with respect to wavenumber is at high resolution...

Smoothed Particle Hydrodynamics (SPH) is widely adopted to predict bird strike events. To improve the parallel computing efficiency of SPH approach, was performed on process a striking fan assembly. Since cube-shaped domains aligned along coordinate axes that are inherent in decomposition algorithm may result low computational efficiency, effect customized data partitioning investigated. The re...

Discretization of spatial derivatives is an important issue in meshfree methods especially when the derivative terms contain non-linear coefficients. In this paper, various methods used for discretization of second-order spatial derivatives are investigated in the context of Smoothed Particle Hydrodynamics. Three popular forms (i.e. ”double summation”, ”second-order kernel derivation”, and ”dif...

We investigate the core mass distribution (CMD) resulting from numerical models of turbulent fragmentation of molecular clouds. In particular we study its dependence on the sonic rms Mach numberMs. We analyze simulations withMs ranging from 1 to 15 to show that, asMs increases, the number of cores increases as well, while their average mass decreases. This stems from the fact that high Mach num...

Abstract While the application of Smoothed Particle Hydrodynamics (SPH) method for modeling welding processes has become increasingly popular in recent years, little is yet known about quantitative predictive capability this method. We propose a novel SPH model simulation tungsten inert gas (TIG) spot process and conduct thorough comparison between our implementation two finite element (FEM)-ba...

In this paper we discuss recent applications of the Smoothed Particle Hydrodynamics (SPH) method to the simulation of supersonic turbulence in the interstellar medium, as well as giving an update on recent algorithmic developments in solving the equations of magnetohydrodynamics (MHD) in SPH. Using high resolution calculations (up to 134 million particles), we find excellent agreement with grid...

In this paper, a new smoothed particle hydrodynamics (SPH) algorithm for simulation of elastic-plastic deformation of solids was proposed. The key point was that materials under highvelocity impact (HVI) behave like fluids. This led to propose a method which was similar to the socalled SPH-projection method, in which the momentum equations are solved as the governing equations. The method consi...

We have been constructed a brand-new radiation hydrodynamics solver based upon Smoothed Particle Hydrodynamics (SPH), which works on parallel computer system. The code is designed to investigate the formation and evolution of the first generation objects at z ∼ 10, where the radiative feedback from various sources play important roles. The code can compute the fraction of chemical species e, H,...
