FLECSPH: The next generation FleCSIble parallel computational infrastructure for smoothed particle hydrodynamics

Abstract

FLECSPH is a smoothed particle hydrodynamics simulation tool, based on the compile-time configurable framework FLECSI. The asynchronous distributed tree topology combined with a fast multipole method allows FLECSPH to efficiently compute hydrodynamics and long range particle–particle interactions. FLECSPH provides initial data generators, particle relaxation techniques, and standard evolution drivers, which can be easily modified and extended to user-specific setups. Data input/output uses the H5part format, compatible with modern visualization software.
