To my surprise, it turns out to be: "This is the ReadMe file for Foil 1.0.2, a Macintosh airfoil generation and display program. Foil 1.0.2 is System 6/7 happy, meaning it should run equally well under both systems. Foil is free, but not public domain. I retain all rights, and it may not be distributed in modified form, or without any of the files. Since it's free, please read the file "A Note About the Author".

Version 2.0 of clawpack is now available from netlib, in pdes/claw. See also the homepage at URL ftp://amath.washington.edu/pub/rjl/programs/clawpack.html There are several new features and applications, and expanded documentation. CLAWPACK -- Conservation LAWs software PACKage ------------------------------------------------ Version 1.0 of CLAWPACK is now available from netlib. This is a package of Fortran subroutines for solving hyperbolic systems of conservation laws in one and two space dimensions. (Future versions should include 3D.) High resolution flux-limiter methods are used, based on solving one-dimensional Riemann problems. In two dimensions, multi-dimensional wave-propagation methods are used. The current version supports only uniform Cartesian grids in rectangular domains, and is intended primarily as a research and teaching tool. The modular form should make it easy to modify and experiment with other methods, as well as to apply it to new problems. The code requires that the user supply a Riemann solver for the problem being solved and also a subroutine that implements the boundary conditions. Source terms can also be handled (via Strang splitting) in which case an ODE solver for the source terms must also be supplied. Several examples of different Riemann solvers are included with the package, including e.g., advection equation, Burgers' equation, Euler equations, isothermal equations, shallow water equations. Various different boundary conditions are also demonstrated, such as periodic, inflow, nonreflecting, and solid walls. Numerous example drivers are included to demonstrate the use of these subroutines. Matlab m-files are included to graphically display the output, or they can be used as a model for writing graphics routines in other languages. Documentation is included in the package, including the postscript file for an introductory paper on the package. The package can be obtained from netlib, where it resides in the library pdes/claw. This directory currently contains: index the index clawpack the basic package, with 1d, 2d routines and many examples doc documentation (postscript files of papers, slides) advection applications of clawpack to 2d advection equations, with examples from a recent paper on this subject (in doc). nozzle application of clawpack to the quasi-1d nozzle problem. vBurgers viscous Burgers' equation, with diffusion equation as source. L-domain L-shaped domains, such as the forward facing step problem. My hope is that a library of more sophisticated applications will be gradually built up, and contributions from other users will be gratefully accepted.The package may be obtained by anonymous ftp from netlib.att.com, where it resides in netlib/pdes/claw. The file netlib/pdes/claw/clawpack.shar is a tar file of the entire directory. Files can also be obtained by sending e-mail to netlib@research.att.com. Send the message "help" to this address for more information. Alternatively, you can obtain files by ftp through Mosaic using the URL ftp://netlib.att.com/netlib/pdes/claw/index.html .

NA Digest Sunday, May 28, 1995 Volume 95 : Issue 22 From: Pat WorleyDate: Wed, 24 May 1995 12:48:20 -0400 Subject: PICL and PSTSWM software updates [snip] PSTSWM PSTSWM v4.0 is now available from http://www.epm.ornl.gov/chammp/pstswm. (It has been available for awhile, but the user guide has just been updated.) PSTSWM is a message-passing benchmark code and parallel algorithm testbed that solves the nonlinear shallow water equations on a rotating sphere using the spectral transform method. PSTSWM was developed by to evaluate parallel algorithms for the spectral transform method as it is used in global atmospheric circulation models. Multiple parallel algorithms are embedded in the code and can be selected at run-time, as can the problem size, number of processors, and data decomposition. This flexibility allows the code to be tuned on a parallel platform before benchmarking, thus evaluating the multiprocessor on its ability to solve the numerical problem rather than it ability to execute a given fixed parallel implementation. Six different problem test cases are also supported, each with associated reference solutions and solution and error analysis options. As of 4/1/95, PSTSWM runs on the Cray Research T3D, the IBM SP-1 and SP-2, the Intel iPSC/2, iPSC/860, DELTA, and Paragon (on both GP and MP nodes and using either the NX or SUNMOS operating systems), the nCUBE/2 and nCUBE/2S, across a network of SUN and IBM workstations, and on a Cray vector machine (as a serial application). Message passing is implemented using MPI, PICL, PVM, and/or native message passing libraries, with the choice being made at compile time. In principle, it should also run on any other platform on which MPI, PICL, or PVM is available. To aid in tuning and in understanding the parallel performance, PSTSWM has been instrumented for the collection of performance data using the PICL trace and profile collection interface. The PICL implementation of the code must be used in order to collect performance data on interprocessor communication but a mixed PICL/native implementation is also provided that can be used to collect data on events not related to message passing. In the mixed implementation, the performance sensitive message passing uses native commands and PICL is only used in the collection of the performance data.

Overview Flux-Corrected Transport (FCT) is a conservative, monotone technique for integrating generalized continuity and hydromagnetic equations. [...] FCT was the first of the class of high-order, monotone schemes for solving generalized continuity equations (e.g., the equations of Eulerian hydrodynamics). An FCT bibliography of basic papers is posted here. A suite of FCT modules with test programs is being developed for posting to the HPCC/ESS Software Exchange. [...] The software for solving 2D hydrodynamical problems will be found in the package LCPFCT2. For 2D magnetohydrodynamical (MHD) applications, the package MHDFCT2 also will be needed. Similar software packages LCPFCT3 and MHDFCT3 eventually will be posted for solving 3D problems. [...] C.

I am surprised you don't have any mention of the NACHOS II code by D. K. Gartling of Sandia National Laboratory, Albuquerque, New Mexico 97185, USA. I had no trouble obtaining a free copy. The code is documented in two reports: "NACHOS II - A Finite Element Computer Program for Incompressible Flow Problems, Part I - Theoretical Background (SAND86-1816 UC-32) and Part II - User's Manual (SAND86-1817 UC-32). The code is written in Fortran. It features triangular and quadrilateral elements, primative variables, with post-processing for stream-function, fluid stress and flux computation. I heard that Gartling was working on a 3D version of Nachos, but I don't know for sure. There should be several other codes from Sandia.

FMS (Fluid Modeling System) is a system for constructing and numerically solving the kinds of equations that arise in general fluid flow problems, i.e. systems of conservation laws. The current version handles flows in one space dimension, plus time. FMS is intended to be a flexible and powerful general purpose tool for this type of modeling. The user supplies FMS with a description of the spatial domain, and the system of equations to be solved, including any boundary conditions or initial conditions, and FMS attempts to compute the the corresponding solution (steady state or time dependant).
The WIND code is a structured, multi-zone, compressible flow solver with flexible turbulence and chemistry models. It is being developed jointly by the NPARC Alliance (the Air Force Arnold Engineering Development Center and NASA Glenn Research Center) and the Boeing Company.

We have developed a free, 2-D CFD program for the Macintosh called QUICK 'n SIMPLE, or "QnS" for short. The program combines a graphical user interface, for specification of the problem, with an iterative control-volume finite-difference solution algorithm to solve two-dimensional convection with diffusion of a passive scalar. It uses either the SIMPLE or SIMPLER coupling algorithms and allows the user to select from three popular upwinding schemes: pure upwinding, power-law differencing scheme (PLDS), and the quadratic upstream interpolation for convective kinematics (QUICK) scheme. As the name implies, the program is designed to be both quick and simple to use. You can check it out, and download a copy if you like, from our web server at http://www.me.pdx.edu/~gerry/QnS If you don't have a web browser, then you can also get a copy via anonymous ftp site at ee.pdx.edu/pub/users/faculty/gerry/QnS, but its not nearly as fun, and you don't get to see our cool examples and tutorial. We have three versions available: 1) 68K, 2) 68K w/ fpu, and 3) PowerMac. The only limit on the size of the problem you can solve is the memory of your Mac. The 68k version (without fpu) can't solve large problems in reasonable amounts of time, but QnS really sings on a PowerMac. The PowerMac version runs over 200 times faster (not a typo) than the 68K version, so a problem which may take 30 seconds on a PowerMac would take nearly two hours on a 68K machine. The fpu version is somewhere in between, but closer in speed to the 68K version. Let us know what you think. Scott J.

Here is the place where you can get a public domain solver for the Navier-Stokes-equations. It is a rather simple Finite-Volume-code but it can solve free-surface-flows. Additionally there is a book available which describes step by step the developement of the code. So the code together with the book is an excellent introduction into CFD and a good basis to develop more enhanced code. The code is available via ftp-server: ftp.lrz-muenchen.de/pub/science/fluiddynamics/cfd/NaSt2D. Solutions of some problems are available from http://www5.informatik.tu-muenchen.de/forschung/visualisierung/praktikum.html. The ReadMe-file from that directory: ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| | | | The 2D CFD Program NaSt2D associated to the book | | | | "Numerische Simulation in der Stroemungsmechanik" | | by M. Griebel, Th. Dornseifer, and T. Neunhoeffer | | Vieweg 1995 | | | | The english translation is published by SIAM | | Title: "Numerical Simulation in Fluid Dynamics" | | | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Remarks: -------- - The program is a 2D solver for the incompressible, transient Navier-Stokes equations including the temperature equation and free boundary problems. It uses finite differences for discretization on a structured equidistant staggered grid, central and upwind (donor-cell) discretization of the convective parts and an explicit time stepping scheme (Chorin's projection method). The free boundary value problems are treated with the MAC technique. - The program was developed for education at a Computer Science Institute. Thus, it is easy to understand and easy to implement but it is not a "state of the art" program. - The files are compressed in PRG.zip. Please uncompress with unzip PRG.zip. Then, the files are located in the directory PRG. Furthermore, the files are available in the directory UNCOMPRESSED. - The program is written in the C programming language. - Compilation of the program with "make". - Used C-compiler is "gcc" (see "makefile") - Run the program by "run" e.g."run dcavity.par". - In the inputfiles "*.par" (examples can be found in the sub-directory "PARAMETER"), the parameters for the program are given, such as the parameters for the discretization, for the fluid, for the initial data,... The inputfile given when starting "run" is read at the beginning of the program. - The following problems are implemented and inputfiles are available in the subdirectory "PARAMETER" * dcavity: Driven Cavity * backstep: Flow over a backward facing step * balken: Flow past an inclined plate * kreis: Flow past a circular obstacle * klappen: Flow through a T-junction * damm: Breaking dam (free boundary value problem FBVP) * tropfen: Splash of a liquid drop (FBVP) * spritzguss: Injection moulding (FBVP) * wafa: Flow over a backward facing step with free surface * convection: Buoyancy flow with heated side walls * fluidtrap: Buoyancy flow with obstacles * rayleigh: Buoyancy flow with heated upper and lower wall (Rayleigh-Benard Flow) - For some problems (e.g. backstep, balken, kreis) the pressure correction does not converge in the first time steps. This is due to the fact that the initial velocity field does not satisfy the continuity equation. - It is possible to store intermediate data in "outfile" specified in the inputfile. Later on, you can use this intermediate data as initial data for continuing your simulation if you specify this file as input-data "infile". - The comments in the code are not very detailed. For a complete description of the code, please see the book. - For the implementation of new problems, it is necessary to write a new inputfile, to modify the boundary data in the function "SETSPECBCOND" in the file "boundary.c" and the definition of the obstacles in "INIT_FLAG" ("init.c"). - Parallelization and turbulence simulation described in the book are not included in this package. - For visualization, we used the graphics tool IDL. Using other visualization software, it might be necessary to adapt the functions "OUTPUTVEC_bin" and "streaklines_bin" in visual.c. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ATTENTION: The program was developed on a HP workstation. There might appear some problems under DOS or WINDOWS95 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ If you have questions, please contact Stephan Knapek Universität Bonn Institut für Angewandte Mathematik Abteilung Wissenschaftliches Rechnen und Numerische Simulation Wegelerstr. 6 D-53115 Bonn e-mail: knapek@iam.uni-bonn.de

DROP V1.1 The program DROP describes the behaviour of individual spherical particles like drops, bubbles or solid particles in multiphase flow situation of a moving fluid. Starting with a force balance on an individual particle, taking into account the relevant fluid-particle interactions, the equation of particle movement in a Lagrangian reference frame is derived. The resulting ODE-system is solved based on a Runge-Kutta algorithm. As a result the velocity versus time or position versus time function can be plotted or data can be written into a file. Boundary conditions regarding the properties of the particle and the fluid can be changed to describe different areas of applications. The program is dialog driven and is running on PC´s with Windows 3.1. The new version DROP V1.1 allows for analysis of accelerating fluid flow in two dimensions.

You can cut and paste the following description : Test Problem Code Archive sod.f -- A f77 program to calculate the exact solution to the Sod shock tube problem. Initial configuration can be easily altered to handle similar shock tube problems. ts.c -- A C program to calculate the exact solution to the Taylor- Sedov blastwave problem. The site is located at http://astron.berkeley.edu/~bobf/archive/index.html.

USGS WATER RESOURCES APPLICATIONS SOFTWARE NOW ON THE WEB A suite of 48 software packages and related materials, used by the U.S. Geological Survey for hydrologic analysis and modeling, is now available for electronic retrieval through an on-line repository on the World Wide Web. The repository is accessible via the WWW from the USGS Water Resources Home Page at: http://h2o.usgs.gov/ by selecting the announcement for "USGS Water Resources Applications Software" or directly at: http://h2o.usgs.gov/software/ In addition, the repository is available via anonymous File Transfer Protocol (FTP) from the USGS Water Resources Information server: h2o.usgs.gov or 130.11.50.175 (path: pub/software) Note: a mirror site (http://www.geogr.uni-jena.de/software/) is available at Friedrich-Schiller University, Department of Geoinformatics, Jena, Germany that some users may find more convenient. FTP access is also available at www.geogr.uni-jena.de (path: pub/software). Each software distribution package consists of compiled or source code, test data sets and documentation files. All of the USGS water resources hydrologic analysis and modeling software applications available publicly on the WWW are documented by published USGS reports. The software distribution packages have been prepared primarily for the Data General AViiON DG/UX platform and for compilation on other UNIX-based computers. The USGS continues to prepare software packages for its own use on UNIX-based and other computer platforms such as DOS-based personal computers. As these packages are available, they will be added to the repository. The software available in the repository is grouped into the following categories: geochemical, ground water, surface water, water quality and general. Examples of the software now available through the on-line repository include: PHREEQC--A program for aqueous geochemical calculations; MOC--Two-dimensional method of characteristics ground-water flow and transport model; MODFLOW--A modular three-dimensional finite-difference ground-water flow model; SUTRA--Saturated and/or unsaturated, constant or variable-density fluid flow, and solute or energy transport (two-dimensional finite element code); ANNIE--Interactive hydrologic (time series) data management; BRANCH--Branch-network one-dimensional dynamic flow model; HSPEXP--Expert system for calibration of the Hydrological Simulation Program--Fortran (HSPF). Since June 1996, when these programs and associated documentation became publicly available on the WWW, the number of accesses by users outside the USGS has increased rapidly. Currently, the site is "visited" about 2500 times per month by users outside the USGS.

The Center for Computational Sciences and Engineering at the Lawrence Berkeley National Laboratory has recently released some CFD software that would be appropriate for the CFD codes list. The software is available from our web site at: http://seesar.lbl.gov/ccse/software/software.html Included are two applications codes: Gas Dynamics AMR - HAMR An adaptive mesh refinement algorithm for solving the compressible Euler equations in two and three dimensions. The code uses an operator-split second-order Godunov algorithm for advancing the flow equations. Single Grid Incompressible Flow Solver - VarDen An incompressible Euler and Navier-Stokes algorithm based on a projection method formulation. There are two and three dimensional versions of the algorithm both of which can treat large-amplitude density variations. Also available are support software libraries BoxLib C++ library C++ class library to support block-structured adaptive algorithms. The applications codes discussed above are based on BoxLib Amrvis visualization tool A visualization tool for viewing data generated by block-structured adaptive algorithms. The above applications generate plot files that can be visualized with AmrVis. AmrVis is also built using BoxLib.
A 3-D Navier-Stokes CFD System
PAB3D solves the three-dimesional Reynolds-averaged Navier-Stokes equations with a finite-volume formulation on structured multi-block grids. Initially developed to predict simple internal and external performance of nozzle-afterbody configurations, the code has evolved to predict complex flow in mixer-ejector nozzles, thrust vectoring, multi-species jet mixing, and propulsion installation with a variety of aerodynamic configurations. The flow solver has a robust (production quality) two-equation k-epsilon turbulence models with anisotropic algebraic Reynolds stress models. PAB3D also has the capability of modeling standard air real-gas effects.

I have recently created an archive of user fortran subroutines for CFX users. The site is located at http://www.uiuc.edu/ph/www/d-creech/cfd/subroutine/index.html
Currently the site contains subroutines that I wrote for my thesis research at the University of Illinois. I am hoping to get submissions from other CFX users, and make the site a useful resource.
The motivation for this site was the difficulty that I had in learing to write subroutines for CFX - there are very few useful examples in the documentation. Hopefully the site will prevent others from having the same problem

MicroTunnel analyzes 2-D subsonic, transonic, and supersonic flow (Mach 0.1 to 3.0) over multi-element configurations on a raster type Cartesian mesh. Flow visualization is provided through color contour plots of local Mach number, density, pressure, and temperature, including streamline plots. Shock waves are easily captured!
MicroTunnel runs out of Microsoft Windows through simple "point and click" operations. While the program is computing, other applications can still be run with minimal sacrifice in performance. Any screen output can be sent to a color printer.
MicroTunnel is based on a finite volume description of the unsteady Euler equations using Van Leer type flux vector splitting. A solution is marched in time from an instantaneous acceleration of the flow. Flow resolutions of 200x150 take approximately six hours to converge to steady state on a system with minimum requirements.

This is the very first public version of MOUSE, a finite volume library. At the Institute of Combustion and Gas Dynamics at the University of Duisburg in Germany, we use this library for CFD applications. Since this is the first public version and it has been restructured quite a bit from the last internal one, it is likely that you discover some bugs if you use it. Nevertheless we think it is in a state where it can be useful. If you discover bugs, please do not hesitate to contact us.
MOUSE is an object oriented framework for finite volume computations on unstructured grids. It serves as a development library, as well as a ready to use application. For more information see http://fire8.vug.uni-duisburg.de/MOUSE/
