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 that the latest official release of version 1.4 of SPHysics is now available.
This code version is the basic version and incorporates the following features:
- 2-D and 3-D versions
- Variable timestep
- Choice of time integration schemes: predictor-corrector, verlet, Beeman
- Choice of two types of solid boundary condition: dynamic and repulsive force
- Periodic open boundary conditions in 3-D
- Choice of:
- Artificial Viscosity
- Laminar Viscosity
- Sub-Particle Scale (SPS) Turbulence Model
- Different Types of Moving Objects (forced motion only)
- Moving Gate
- Wavemaker
- Sliding Wedge
- Visualization routines using Matlab or ParaView
- New Options:
- Density Reinitialization using Shepard or Moving Least Squares (MLS)
- RESTART option to stop and restart simulations
- Capability for different Equations of State
From version 1.2 includes faster linked lists and core subroutines.
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 of dam-breaks on off-shore structures. 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
- kernel gradient corrections
- parallelization
- couple SPHysics to long wave propagation model
- high performance (accelerating the code) using GPU computing (CUDA)
Different new codes will be released soon:
- SPHysics_v1.6
- Parallel-SPHysics_v1.0
- Funwave-SPHysics hybrid model_v1.0
- GPU-SPHysics_v1.0
