Welcome to Spheral’s documentation!

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.
