Overview

The NPARC Alliance flow simulation system is distributed to users as a collection of compressed tar files, containing Wind-US and several pre- and post-processing tools. Both Wind-US and the tools are available in two different "distributions" - an application distribution and a build distribution. The application distributions are intended for those who will be running the codes, but will not be modifying them. The build distributions are intended for those who must build the executables themselves, either to run on a computational platform not currently supported by the NPARC Alliance, or to include some compile-time option not present in the application distribution. [Developers also have access to a development distribution. This is discussed in the Development Environment section of the Wind-US Developer's Reference, accessible only to registered Wind-US developers.]

Wind-US Application Distribution

The Wind-US application distribution includes all the executable programs and scripts necessary to run Wind-US on a supported computational platform. Due to limited resources, pre-compiled Wind-US 2.0 executables are currently only available for 32-bit and 64-bit Linux systems.

The application distribution includes PVM but not MPI, and the Wind-US executable was built assuming that PVM message passing will be used for parallel runs. If Wind-US is to be run on a multi-processor system using MPI, you'll need to build the Wind-US executable yourself using the build distribution, and link with the locally-installed MPI libraries.

Tools Application Distribution

A tools application distribution includes all the executable programs and scripts necessary to run one or more of the various pre- and post-processing tools on a supported computational platform. This includes:

• GMAN, a pre-processor used for setting boundary conditions and multi-zone connectivity
• MADCAP, currently used primarily as a successor to GMAN, and when fully implemented will allow access under one user interface to the full range of tools and processes used to perform CFD analyses
• CFPOST, a post-processor used to list and plot results, generate reports, and produce files for other post-processors.
• A variety of smaller utilities, described in the Wind-US Utilities Guide.

Pre-compiled tools executables are generally available for the same platforms as Wind-US.

Wind-US Build Distribution

The Wind-US build distribution contains all the files needed to build and install Wind-US on a variety of platforms. This includes:

• Source code for the Wind-US flow solver
• Source code for all the required library routines, including PVM
• Scripts needed to run Wind-US
• Makefiles for a variety of computational platforms

Tools Build Distribution

A tools build distribution contains all the files needed to build and install one or more of the tools on a variety of platforms. This includes:

• Source code for the tool(s)
• Source code for all the required library routines
• Scripts needed to run the tool(s)
• Makefiles for a variety of computational platforms
