I ran it for high-mass stars and low-mass stars, for stars born exceedingly hot and those born relatively cold. I ran it assuming the superfluid currents beneath the crust to be absent – not because I wanted to know the answer, but because I had d...

In this paper, we present a Smoothed Particle Hydrodynamics (SPH) implementation algorithm on GPUs. To compute a force on a particle, neighboring particles have to be searched. However, implementation of a neighboring particle search on GPUs is not straightforward. We developed a method that can search for neighboring particles on GPUs, which enabled us to implement the SPH simulation entirely ...

This paper presents an overview and introduction to Smoothed Particle Hydrodynamics and Magnetohydrodynamics in theory and in practice. Firstly, we give a basic grounding in the fundamentals of SPH, showing how the equations of motion and energy can be self-consistently derived from the density estimate. We then show how to interpret these equations using the basic SPH interpolation formulae an...

The magnetorotational instability (MRI) is an important process in driving turbulence sufficiently ionized accretion disks. It has been extensively studied using simulations with Eulerian grid codes, but remains fairly unexplored for meshless codes. Here, we present a thorough numerical study on the MRI smoothed particle magnetohydrodynamics method geometric density average force expression. We...

We propose a particle-based method to simulate thin-film fluid that jointly facilitates aggressive surface deformation and vigorous tangential flows. build our dynamics model from the tension driven Navier-Stokes equation with dimensionality reduced using asymptotic lubrication theory customize set of differential operators based on weakly compressible Smoothed Particle Hydrodynamics (SPH) for ...
