The SPHYSICS Code

SPHYSICS is a Smoothed Particle Hydrodynamics (SPH) code inspired by the formulation of Monaghan (1992) developed jointly by researchers at the Johns Hopkins University (U.S.A.), the University of Vigo (Spain), the University of Manchester (U.K.) and the University of Rome La Sapienza (Italy). We are excited to announce the official release of version 1.0 of SPHYSICS will be on 1st AUGUST 2007.

This code version is the basic version and incorporates the following features:

• 2-D and 3-D versions
• Linked lists for fast particle connectivity
• Choice of two types of solid boundary condition: dynamic and repulsive force
• Periodic open boundary conditions
• Choice of:
  • Artificial Viscosity
  • Laminar Viscosity
  • Sub-Particle Scale (SPS) Turbulence Model
• Different Types of Moving Objects (forced motion only)
  • Wavemaker
  • Sliding Wedge
  • Moving Gate
• Visualization routines using Matlab or ParaView

The code has been developed over a number of years primarily to study free-surface flow phenomena where Eulerian methods can be difficult to apply, such as waves, impact on dams, off-shore. Furthermore, the meshfree technique facilitates the simulation of highly distorted fluids/bodies.

Future Developments

Extensions of the code are already underway to add the following features to the SPHYSICS code

• floating bodies
• parallelization
• couple SPHYSICS to long wave propagation model
