Spheral++ provides a steerable parallel environment for performing coupled hydrodynamical & gravitational numerical simulations. Hydrodynamics and gravity are modelled using particle based methods (SPH and N-Body).

Some useful features are

  • Total energy conserving compatible hydro mode.
  • ASPH (Adapative Smoothed Particle Hydrodynamics) algorithm.
  • CRKSPH (Conservative Reproducing Kernel Hydrodyamics) is also available.
  • Oct-tree based N-Body gravity.
  • Fluid and solid material modeling.
  • Damage and fracture modeling in solids.
  • Scriptable user interface in python.
  • Extensible by user in python, including the ability to write new physics packages in python.
