In this paper, we present an open-source multi-resolution and multi-physics library: SPHinXsys (pronunciation: sfinksis) which is an acronym for underline{S}moothed underline{P}article underline{H}ydrodynamics (SPH) for underline{in}dustrial compleunderline{X} underline{sys}tems. As an open-source library, SPHinXsys is developed and released under the terms of Apache License (2.0). Along with the source code, a complete documentation is also distributed to make the compilation and execution easy. SPHinXsys aims at modeling coupled multi-physics industrial dynamic systems including fluids, solids, multi-body dynamics and beyond, in a multi-resolution unified SPH framework. As an SPH solver, SPHinXsys has many advantages namely, (1) the generic design provides a C++ API showing a very good flexibility when building domain-specific applications, (2) numerous industrial or scientific applications can be coupled within the same framework and (3) with the open-source philosophy, the community of users can collaborate and improve the library. SPHinXsys presently (v0.2.0) includes validations and applications in the fields of fluid dynamics, solid dynamics, thermal and mass diffusion, reaction-diffusion, electromechanics and fluid-structure interactions (FSI).
The radiation hydrodynamics equations for smoothed particle hydrodynamics are derived by operator splitting the radiation and hydrodynamics terms, including necessary terms for material motion, and discretizing each of the sets of equations separatel
MFC is an open-source tool for solving multi-component, multi-phase, and bubbly compressible flows. It is capable of efficiently solving a wide range of flows, including droplet atomization, shock-bubble interaction, and gas bubble cavitation. We pre
We present a novel method for particle splitting in smoothed particle hydrodynamics simulations. Our method utilizes the Voronoi diagram for a given particle set to determine the position of fine daughter particles. We perform several test simulation
We describe a strategy for code modernisation of Gadget, a widely used community code for computational astrophysics. The focus of this work is on node-level performance optimisation, targeting current multi/many-core IntelR architectures. We identif
In this paper, we present a new formulation of smoothed particle hydrodynamics (SPH), which, unlike the standard SPH (SSPH), is well-behaved at the contact discontinuity. The SSPH scheme cannot handle discontinuities in density (e.g. the contact disc
