A direct primitive variable recovery scheme for hyperbolic conservative equations: the case of relativistic hydrodynamics [PDF]
, 2018 In this article we develop a Primitive Variable Recovery Scheme (PVRS) to solve any system of coupled differential conservative equations. This method obtains directly the primitive variables applying the chain rule to the time term of the conservative ...

Smooth Particle Hydrodynamics Simulation of Micro-Cup-Extrusion Using a Graphit-ic Coating
Advances in Materials Science and Engineering, 2014 Microextrusion is becoming increasingly important for the manufacturing of microcomponents. However, this reduction in scale to a microlevel means that the influence of friction and the need for suitable lubrication are greatly increased.

Hybrid smoothed particle hydrodynamics [PDF]
Proceedings of the 2011 ACM SIGGRAPH/Eurographics Symposium on Computer Animation, 2011 We present a new algorithm for enforcing incompressibility for Smoothed Particle Hydrodynamics (SPH) by preserving uniform density across the domain. We propose a hybrid method that uses a Poisson solve on a coarse grid to enforce a divergence free velocity field, followed by a local density correction of the particles.
