MODEL PURPOSE AND STRUCTURE SSIIM is an abbreviation for Sediment Simulation In Intakes with Multiblock option. The program is made for use in River/Environmental /Hydraulic/Sedimentation Engineering. The main motivation for the program was to simulate the sediment movements in general river/channel geometries. This has shown to be difficult to do in physical model studies for fine sediments. The program solves the Navier-Stokes equations with the k-epsilon model on a three-dimensional almost general non-orthogonal grid. The grid is structured. A control volume method is used for the discretization, together with the power-law scheme or the second order upwind scheme. The SIMPLE method is used for the pressure coupling. The velocity field is used when solving the convection-diffusion equations for concentrations of different sediment sizes. This gives trap efficiency and sediment deposition pattern. The calculations can be time-dependent with an adaptive grid moving vertically to account for changes in water and bed level. Additions to version 1.4 includes a water quality module which solves the convection-diffusion equation for a number of water quality constituents. The source/sink terms for the biochemical reactions can be specified by the user. The model has a user interface with capabilities of presenting graphical plots of velocity vectors, contour plots, particle animations and 2D and 3D OpenGL graphics with colorshading. By using global variables and multi-threading, the graphics can be seen while the numerial calculations are running. The model includes several utilities which makes it easier to give input data. The most commonly used data can be given in dialog boxes. There is an interactive graphical grid editor with elliptic and transfinite interpolation. The grid and some of the input data can be changed while the numerical calculations are running. Examples of results from SSIIM can be found at the WWW page: http://www.sintef.no/nhl/vass/vassdrag.html AVAILABILITY SSIIM version 1.4 is freeware. It can be dowloaded 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 OPERATING SYSTEM: The program runs only under OS/2 Warp 4.0 and later versions.

INTRODUCING THE LABORATORY FOR COMPUTATIONAL ASTROPHYSICS The LCA is a joint venture between the NSF, the National Center for Supercomputing Applications, and the Department of Astronomy at the University of Illinois, Urbana-Champaign. Its purpose is to develop and disseminate numerical algorithms and community codes for CFD, primarily for astrophysics. The LCA currently provides the following packages: * ZEUS-2D: a one- or two-dimensional (moving) Eulerian grid code for radiation magnetohydrodynamics. * ZEUS-3D: a one-, two- or three-dimensional explicit (moving) Eulerian grid code for magnetohydrodynamics. * TITAN: a one-dimensional implicit adaptive mesh code for radiation hydrodynamics. * 4D2: an interactive tool for visualizing and animating 3D data (array, particle) on Silicon Graphics workstations. The community application codes (ZEUS-2D, ZEUS-3D, TITAN) are available free of charge to academic researchers.

Subject: Software for 3-D Fluid Interfaces Available
Software for simulating the 3-D fluid interface instabilities in compressible fluids (Rayleigh-Taylor and Richymyer-Meshkov instabilities) is available to those who are interested in applying it to scieitific problems.
This code uses a resolution enhanced numerical scheme for contact surface, that is, the second order TVD with artificial compression (TVD/AC). The fluid contact interface is traced through the level set method. The code has both the seriel and parallel modes and can be run in parallel and distributed system such as the iPSC-860 and the PVM. The output features the triangulated surface which can be viewed by using the geomview software package.
For detail and to obtain this code, please send email to: firstname.lastname@example.org.

GASDYN solves the Euler equations of gas dynamics in two and three dimensions using spatial finite differences and either the Rusanov or System Upwind time advancement algorithms. Ionization and laser heating of the neutral gas are included through the Saha equation and a source term in the energy equation. GASDYN has been implemented in parallel using PVM to maximize its portability. GASDYN is being used to model expansion and transport of the vapor plume produced during laser ablation of materials for thin film deposition.

PHASES is a general purpose software package which numerically simulates fluid flow and heat - mass transfer processes in engineering applications. PHASES features include: (i) incompressible, two-phase and multiconstituent flow models, (ii) Windows95, Windows 3.1 and Windows NT compatibility, (iii) 32 bit compiler source code execution, (iv) realtime simulations, (v) powerful graphics libraries and data editors, (vi) finite element mesh generation with mouse-driven commands and (vii) several numerical analysis utilities. The numerical method employs finite volume - element models, implicit solutions, collocated variable storage and a simultaneous velocity - pressure coupling. The two-phase flow models incorporate a homogeneous, mixture formulation which includes species transport and elliptic grid transformations for volumetric shrinkage / expansion flows during solid - liquid phase transition. PHASES has special applications in materials processing industries. Additional industrial applications appear in fields such as aerodynamics, external flows, heat exchanger design, internal flows in pipes and ducts and heat transfer in buildings.
