We present a detailed study of the hydrodynamical interactions in a Newtonian black hole–neutron star binary during the last stages of inspiral. We consider close binaries which are tidally locked, use a stiff equation of state (with an adiabatic index Γ = 3) throughout, and explore the effect of different initial mass ratios on the evolution of the system. We calculate the gravitational radiat...

We provide a description of the SNSPH code—a parallel 3-dimensional radiation hydrodynamics code implementing treecode gravity, smooth particle hydrodynamics, and flux-limited diffusion transport schemes. We provide descriptions of the physics and parallelization techniques for this code. We present performance results on a suite of code tests (both standard and new), showing the versatility of...

We describe a newly developed cosmological hydrodynamics code based on the weighted essentially non-oscillatory (WENO) schemes for hyperbolic conservation laws. High order finite difference WENO schemes are designed for problems with piecewise smooth solutions containing discontinuities, and have been successful in applications for problems involving both shocks and complicated smooth solution ...

This paper presents a novel Smooth Particle Hydrodynamics computational framework for the simulation of large strain fast solid dynamics in thermo-elasticity. The formulation is based on Total Lagrangian description system first order conservation laws written terms linear momentum, triplet deformation measures (also known as minors gradient tensor) and total energy system, extending thus previ...

A Lagrangian particle-based method, the smooth particle hydrodynamics, is used to model the flow of ultra-highperformance, self-compacting concretes containing short steel fibres which behave like a non-Newtonian fluid described by a Bingham-type constitutive model. An incompressible smooth particle hydrodynamics method is used to simulate the flow after the kink in the shear stress against the...
