WHAT THE PROGRAM DOES:
The SSIIM program is made for use in River/Environmental/Hydraulic/
Sedimentation Engineering. It calculates water, sediment flow and water
quality in three dimensions, solving the Navier-Stokes equations with the
k-epsilon turbulence model. The convection-diffusion equations are solved to
calculate sediment transport and water quality constituent transport. The
calculations are time-dependent and an adaptive grid moves vertically to
account for changes in water and bed level.
The program includes graphical pre and post processors including an
interactive grid editor, vector and contour plots, particle animations and 2D
and 3D OpenGL graphics with colorshading.
The various modules can run simultaneously by using the multi-threading
possibilities of OS/2. It is therefore possible to view the preliminary
results and/or interactively change the grid and input data while the
numerical calculations are running.
Examples of results from SSIIM can be found at the WWW page:

AVAILABILITY
SSIIM version 1.4 is freeware. It has been uploaded to the HOBBES system,
which means that it can be downloaded from for example:
wcarchive.cdrom.com directory /.1/os2/wpsutil/ssiim14.zip
boris.infomagic.com directory /pub/mirrors/Hobbes/wpsutil/ssiim14.zip
hobbes.nmsu.edu directory /os2/wpsutil/ssiim14.zip
wuarchive.wustl.edu directory /systems/os2/wpsutil/ssiim14.zip
CHANGES FROM VERSION 1.3 TO VERSION 1.4:
Version 1.4 replaces version 1.3. The main changes are:
- 2D depth-averaged water flow calculation added
- water quality module
- time-dependent calculations
- OpenGL graphics
- On-line User's Manual
OPERATING SYSTEM:
The program runs only under OS/2 Warp 4.0 and later versions.
CONTENT OF SSIIM14.ZIP
- "readme.ssi" : readme file
- "manual14.lwp" : User's Manual, written in Lotus Word Pro
- "ssiim14.inf" : On-line User's Manual
- "ssiim14.exe" : executable file, optimized for the Pentium processor
In addition there are input files for eight examples:
- Channels crossing
