* SPHinXsys (pronunciation: s'finksis) is an acronym from Smoothed Particle *
* Hydrodynamics for industrial compleX systems. It provides C++ APIs for    *
* physical accurate simulation and aims to model coupled industrial dynamic *
* systems including fluid, solid, multi-body dynamics and beyond with SPH   *
* (smoothed particle hydrodynamics), a meshless computational method using  *
* particle discretization.                                                  *
*                                                                           *
* SPHinXsys is partially funded by German Research Foundation               *
* (Deutsche Forschungsgemeinschaft) DFG HU1527/6-1, HU1527/10-1             *
