PAB3D solves the three-dimensional Reynolds-averaged Navier-Stokes equations with a finite-volume formulation on structured multi-block grids. The PAB3D code was developed at NASA Langley Research Center under NASA Contract NAS1-19831 and the United States Government retains certain rights. The National Aeronautics and Space Administration, Langely Research Center (NASA LaRC), acting under the authority of the National Aeronautics and Space Act of 1958, as amended, and Analytical Services & Materials, Inc. (AS&M), jointly executed a Memorandum of Agreement (MOA) in order to foster commercialization of the PAB3D software code. The PAB3D code is part of the CFD Resources at NASA Langley. 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. The code is capable of working in multiprocessors and distributed computer systems (CFD on Inexpensive Clustered Computers). This code has been used to simulate complex aerodynamic flow configurations and is currently being used in several national programs.

For limited time, you can receive our 3-D Navier-Stokes solver PAB3D limited edition free of charge. The limited edition will have all the options except it will limit the problem size to 500,000 grid points and the number of distributed computer to 4. If you are interested, please fill the download registration form at http://www.eagle.com/demopab3d.html. Shortly, you will receive an e-mail with the software or the website which you can download the software and utilities. We have tested the PAB3D using several OS such as LINUX, MAC, WINDOWS, SGI, SUN, and HP. http://www.asm-usa.com/software/ASM-PAB3D.html
