What is SPHysics and what can it do?
SPHysics is a Smoothed Particle Hydrodynamics (SPH) code written in fortran for the simulation of potentially violent free-surface hydrodynamics. For release version 1.0, the SPHysics code can simulate various phenomena including wave breaking, dam breaks, sloshing, sliding objects, wave impact on a structure, etc.What platforms does SPHysics run on?
The SPHysics source code can run on any operating system or platform where you have a Fortran compiler. During development every effort has been made to ensure that the SPHysics code is as portable as possible. The code has been tested on the following operating systems and compilers: Windows: Compaq Visual Fortran; Linux: GPL gfortran compiler, Intel fortran compiler; Mac: GPL gfortran;What does SPHysics need as input?
As input, you specify which compiler you wish to use: gfortran or Intel fortranWhat does SPHysics create as output?
A raw data file is written; code is also provided for visualizing the results.Are there any restrictions on SPHysics use?
The source code for SPHYSICS is freely redistributable under the terms of the GNU General Public License (GPL) as published by the Free Software FoundationHow do I visualize the results?
Basic visualization tools are included with the source code, allowing results to be visualized with either Matlab or ParaView. In order to use ParaView, the raw data files require some processing, which at present is done using Matlab code; this will be converted to fortran source code soon.What if I find a bug in the code?
A good rule of thumb is that in a commerical code there is a bug every 100 lines of code. If you find a bug in the SPHysics code, please let the developers know, using the Discussion Forum.How can I contribute to the development of SPHysics?
For starters you can buy the main developers a drink of beer at the next conference or workshop. Failing that, you can post any new subroutines that you want to share with other users to the Forum. The core developers of SPHysics meet periodically to discuss future developments and directions. If your new subroutines are considered to be an invaluable addition to the code, they will be considered for inclusion in the next release version.
