| SWAN
source code The source code of SWAN 40.85 can be downloaded here. This distribution may be implemented on Microsoft Windows, Linux, Unix and Mac OS/X, provided a Fortran compiler is available. Please consult the enclosed README files. Detailed information on implementation of SWAN on your computer can be found in the Implementation Manual. Please refer to this page for possible bug fixes. SWAN binaries for MS Windows Binary distributions of SWAN 40.85 for Windows XP/Vista/7 are also provided. Both 32-bit and 64-bit version of SWAN are available and follow OpenMP 2.0 standard. This will be particularly useful for those users who have a dual core PC. As a rough guide, you can expect to half your turn-around time on a dual core when comparing against a single core. The 64-bit version requires an x64 edition of Windows XP, Vista or Windows 7. It cannot be installed on a 32-bit OS, even if it is hosted on a 64-bit computer. To install SWAN on your Windows PC, download and run the Setup Wizard (size: 2.42 MB). For your convenience, both the batch and edit files are included. Manuals The information about the SWAN package is distributed over four different documents. The User Manual describes the complete input and usage of the SWAN package. The Implementation Manual explains the installation procedure of SWAN on a single- or multi-processor machine with shared or distributed memory. The Programming rules is meant for programmers who want to develop SWAN. The Scientific/technical documentation discusses the physical and mathematical details and the discretizations that are used in the SWAN program. These documents are available in PDF format. You can download the PDF manuals here. The documents are also available online. These documents are written in LaTeX format. If you are new to LaTeX, we recommend to read first the manual LaTeX for dummies. Utilities Conversion programs are provided to convert the old 1D and 2D spectra files generated by a SWAN version older than 40.00 into the current format. Test cases Four examples of test cases can be downloaded for your own purpose of testing SWAN on your computer. These examples consist of command files and data. Three examples are academic tests: a refraction test, a slanted current test and a diffraction test. The other example is the Haringvliet field case. Detailed documentation on these tests can be found in Ris et al. (1999): A third-generation wave model for coastal regions, Part II: Verification, J. Geoph. Res., C4, 104, 7997-7681 and Holthuijsen et al. (2003): Phase-decoupled refraction-diffraction for spectral wave models, Coast. Engng., 49, 291-305. Since version 40.72, use of unstructured grids can be handled as well. Only triangular meshes may be employed. For the Haringvliet case, an example of unstructured grid is provided. The resolution of this grid depends on the bathymetry and has been constructed by means of the Matlab interface BatTri. (This program, however, called Triangle for the actual grid generation.) The results of this test case are provided as well. You may plot the grid and the maps of several wave parameters in Matlab by means of the Matlab scripts plotgrid.m and plotunswan.m. The examples are complete with output files from our own test runs. These results can be compared on one hand with the analytical solutions that are supplied in numerical form and on the other hand observations at several buoy locations for the Haringvliet case. Old SWAN versions There are seven old (non-supported) versions of SWAN available for download: SWAN 40.81 This is the previous stable release of SWAN. SWAN 40.72ABCDE This is an older stable release of SWAN supporting unstructured grids. SWAN 40.51AB This is an older stable release of SWAN. SWAN 40.41AB This is a quite older stable release of SWAN. SWAN 40.31ABCDEFGH This is a much older stable release of SWAN. SWAN 40.20 This version is less stable, although still reliable. However, version 40.20 is not recommended because the SWAN source code has seen a lot of changes, bugfixes and new features since then. SWAN 40.11ABCDEF This non-GNU version is antique. The source code is not parallelized and is therefore not recommended for large production runs. |
