Local Polynomial Regression and Filtering for a Versatile Mesh‐Free PDE Solver

International Journal for Numerical Methods in Fluids, EarlyView.
A high‐order, mesh‐free finite difference method for solving differential equations is presented. Both derivative approximation and scheme stabilisation is carried out by parametric or non‐parametric local polynomial regression, making the resulting numerical method accurate, simple and versatile. Numerous numerical benchmark tests are investigated for

Moving Particle Semi-implicit Method in Simulating Water-Oil Penetration

Indonesian Journal of Physics, 2019
In this study, the simulation of water-oil penetration has been performed by using the MPS method. The MPS method has been utilized to simulate the two-dimensional water-oil penetration and to observe the interaction of those liquids. This water-oil penetration phenomenon can be applied to the case of nuclear reactors.

Truncation Error Analysis of Approximate Operators for a Moving Particle Semi-Implicit Method

, 2019
This paper considers several approximate operators used in a particle method based on a Voronoi diagram. Under some assumptions on a weight function, we derive truncation error estimates for our approximate gradient and Laplace operators.

An efficient implementation of massive neutrinos in non-linear structure formation simulations

, 2012
Massive neutrinos make up a fraction of the dark matter, but due to their large thermal velocities, cluster significantly less than cold dark matter (CDM) on small scales.
