A Coupled Analysis of Incompressible Fluid and Hard Sphere using ALE method

Abstract

The author is developing an incompressible viscous fluid analysis system (ADVENTURE_Fluid) which contains the Q1-P0 hexahedral element solver with the BTD method and matrix storage free technique and the P1-P1 tetrahedral element solver with the SUPG/PSPG stabilization method. In this paper, the author demonstrates a coupled analysis of incompressible fluid and hard sphere using the ALE method. Three mesh control strategies are compared for evaluating the efficiency and the suitability for parallel processing.
