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. More information on the technical capabilities can be found on the SPHYSICS home page.
Where can I download SPHYSICS?
Please see the Downloads Page.
Who wrote SPHYSICS?
SPHYSICS was written by a number of contributors from universities from around the world.....
What platforms does SPHYSICS run on?
The SPHYSICS source code is downloadable from the main Downloads page. Therefore, the code can run on any operating system or platform where you have a fortran compiler. (please see the following webpage for fortran compilers available on the internet). 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
How do I run SPHYSICS on windows?
This depends whether you are using an Intergrated Development Environment (IDE). Generally, your compiler will produce SPHYSICS.exe which are then run from the command line:
SPHYSICS.exe
How do I run SPHYSICS on Linux
The SPHYSICS code comes with batch files which are used to compile the source code and then run the codes. For example, for Case1 which is supplied with the code (under run_directory), at the command prompt, type:
./Test1.bat
How do I visualize the results?
For which cases has SPHYSICS been validated?
The code has been validated for a number of different test cases including dam breaks, waves hitting structures, breaking waves at beaches, Poiseuille flow, Couette flow. Interested readers are referred to the following publications for more detailed information Publication list.
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 Forum pages (DO NOT email the developers directly!)
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 pages. Periodically the core developers of SPHYSICS will meet and discuss future developments and directions of SPHYSICS. 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.
