Efficient and Accurate Adaptive Resolution for Weakly-Compressible SPH

  title={Efficient and Accurate Adaptive Resolution for Weakly-Compressible SPH},
  author={Abhinav Muta and Prabhu Ramachandran},
In this paper we propose an accurate, and computationally efficient method for incorporating adaptive spatial resolution into weakly-compressible Smoothed Particle Hydrodynamics (SPH) schemes. Particles are adaptively split and merged in an accurate manner. Critically, the method ensures that the number of neighbors of each particle is optimal, leading to an efficient algorithm. A set of background particles is used to specify either geometrybased spatial resolution, where the resolution is a… 
Parallel adaptive weakly-compressible SPH for complex moving geometries
The use of adaptive spatial resolution to simulate flows of practical interest using Smoothed Particle Hydrodynamics (SPH) is of considerable importance. Recently, Muta and Ramachandran [1] have
A family of second order convergent weakly-compressible SPH schemes
A systematic numerical study of convergence and accuracy of kernel-based approximation, discretization operators, and weaklycompressible SPH (WCSPH) schemes and proposes several new variations of the basic WCSPH scheme that are all second-order accurate.


A local adaptive discretization algorithm for Smoothed Particle Hydrodynamics
In this paper, an extension to the Smoothed Particle Hydrodynamics (SPH) method is proposed that allows for an adaptation of the discretization level of a simulated continuum at runtime. By combining
A new class of accurate, mesh-free hydrodynamic simulation methods
We present two new Lagrangian methods for hydrodynamics, in a systematic comparison with moving-mesh, smoothed particle hydrodynamics (SPH), and stationary (non-moving) grid methods. The new methods
Algorithms for uniform particle initialization in domains with complex boundaries
This paper proposes an improved SPH-based algorithm which produces uniform particle distributions of both the fluid and solid domains in two and three dimensions and demonstrates the accuracy of the new algorithm by constructing some challenging geometries.
A consistent spatially adaptive smoothed particle hydrodynamics method for fluid–structure interactions
The key ingredients in the method are a posteriori error estimator/distance-based criterion of adaptivity and a particle-shifting technique and it accelerates the FSI solution as the adaptive approach leads to fewer degrees of freedom without sacrificing accuracy.
Adaptive resolution for multiphase smoothed particle hydrodynamics
Numerical validations have proven that the present adaptive resolution method can accurately capture the dynamics of liquid–gas interface with low computational costs and can be incorporated into other particle-based methods for efficient fluid dynamics simulation.
Variable resolution for SPH: A dynamic particle coalescing and splitting scheme
Abstract In this paper a novel variable resolution method using particle splitting and coalescing for the SPH numerical solution of the Navier–Stokes equations is presented. The key idea of the
Variable resolution for SPH in three dimensions: Towards optimal splitting and coalescing for dynamic adaptivity
Abstract As smoothed particle hydrodynamics (SPH) becomes increasingly popular for complex flow analysis the need to improve efficiency particularly for 3-D problems is becoming greater. Automatic
A corrected transport-velocity formulation for fluid and structural mechanics with SPH
Particle shifting techniques (PST) have been used to improve the accuracy of the Smoothed Particle Hydrodynamics (SPH) method. Shifting ensures that the particles are distributed homogeneously in
An advanced study on discretization-error-based adaptivity in Smoothed Particle Hydrodynamics
A novel, purely methodological strategy enabling to automatically adjust the local spatial resolution in Smoothed Particle Hydrodynamics (SPH) is built upon the fact that the accuracy of the SPH interpolation is related to zeroth- and first-order moments.

Abstract In the present work a consistent inclusion of a particle shifting technique (PST) in the weakly compressible Smoothed Particle Hydrodynamic (SPH) models is discussed. Recently, it has been
