This package implements smoothed particle hydrodynamics (SPH) in LAMMPS. Currently, the package has the following features:

• Tait, ideal gas, Lennard-Jones equation of states, full support for complete (i.e. internal-energy dependent) equations of state
• plain or Monaghans XSPH integration of the equations of motion
• density continuity or density summation to propagate the density field
• commands to set internal energy and density of particles from the input script
• output commands to access internal energy and density for dumping and thermo output

See the file doc/USER/sph/SPH_LAMMPS_userguide.pdf to get started.

There are example scripts for using this package in examples/USER/sph.

The person who created this package is Georg Ganzenmuller at the Fraunhofer-Institute for High-Speed Dynamics, Ernst Mach Institute in Germany (georg.ganzenmueller at emi.fhg.de). Contact him directly if you have questions.
