The Sediment Simulation In Intakes with Multiblock option model (SSIIM) is for teaching and research for hydraulic/river/sedimentation engineering. It solves the Navier-Stokes equations using the control volume method with the SIMPLE algorithm and the k-epsilon turbulence model. It also solves the convection-diffusion equation for sediment transport, using van Rijn's formula for the bed boundary. A water quality module is included.
The software application has an interactive graphical grid editor creating a structured grid. The post-processor includes vector graphics, contour plots, profiles, etc which can run simultaneously with the solver, enabling viewing of intermediate result. A post-processor viewing coloured surfaces in 3D is also made, as a separate program.
The software has been around for a while, but a new version for MS Windows has been recently released (2007 September 26), so I thought I would post on it. (I have not tried the latest release, but it would need to be a signficant improvement for SSIIM to have surpassed CCHE2D).
