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

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
TLDR
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
TLDR
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
TLDR
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.

TLDR
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.
