Query: SPHinXsys: an open-source multi-physics and multi-resolution library
  based on smoothed particle hydrodynamics   In this paper, we present an open-source multi-resolution and multi-physics
library: SPHinXsys (pronunciation: s'finksis) which is an acronym for
\underline{S}moothed \underline{P}article \underline{H}ydrodynamics (SPH) for
\underline{in}dustrial comple\underline{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).
