A drawback of the Smoothed Particle Hydrodynamics (SPH) method is its computational effort. An intuitive way to reduce the calculation time, is to use SPH only in parts of the problem domain where it is necessary, e.g. in a region where interfaces are present, because of the advantages of SPH for multiphase flow. In other parts of the problem domain, e.g. in a region of simple flow, a cheap met...

A new multi-stage three-dimensional transient computational model to simulate powder bed fusion (L-PBF) additive manufacturing (AM) processes is presented. The uses the discrete element method (DEM) for flow simulation, an extended smoothed particle hydrodynamics (SPH) melt pool dynamics and a semi-empirical microstructure evolution strategy evolving temperature of non-spherical Ti-6Al-4V grain...

A two-way coupling between the Smoothed Particle Hydrodynamics-based (SPH) code with a multiphysics library to solve complex fluid-solid interaction problems is proposed. This work provides full access package for use of this by releasing source code, completed guidelines its compilation and utilization, self-contained template setups practical uses novel implemented features, provided here. Th...

The naturally occurring second messenger sphingosine (SPH) was examined for its ability to influence cardiac myocyte Ca2+ regulation. SPH inhibited intracellular Ca2+ transients in adult and neonatal rat ventricular myocytes. The inhibition was steeply dose dependent, with complete blockage of the Ca2+ transients occurring in the 20- to 25-mumol/L range. Whole-cell patch clamping revealed subst...

Our mesoscale simulation method [M. Robinson, S. Luding, and M. Ramaioli, submitted (2013)] for multiphase fluid-particle flows couples Smoothed Particle Hydrodynamics (SPH) and the Discrete Element Method (DEM) and enjoys the flexibility of meshless methods, such as being capable to handling free surface flows or flow around complex and/or moving geometries. We use this method to simulate thre...

In this study, the seismic response of shallow foundations resting on a liquefiable soil layer is modeled using coupled smoothed particle hydrodynamics (SPH)-discrete element method (DEM) scheme. framework, deposit represented by an assembly DEM particles and fluid domain lumped into set SPH carrying local properties.
