Development of smoothed particle hydrodynamics method for modeling active nematics

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, its slope different length scales discussed. To exploit capabilities, pathlines particles evaluated during simulation. Finally, mixing behavior nematics as well described qualitatively. effects two important parameters, namely, activity elastic constant investigated. It shown that intensifies chaotic nature nematics, while behaves oppositely.
