CFPOST User's Guide

CFPOST is a post-processor that may be used to examine the contents of the Common Flow (.cfl) file created by Wind-US. It includes options to list and plot results, generate reports, and produce files for other post-processors.

The PDF form of the CFPOST User's Guide (532K, 109 pages) was created using pdfTeX and the hyperref package, and is designed to be printed. The PDF file may be viewed and/or printed using a variety of freely available software packages, including Acrobat Reader , GhostScript , and xpdf . The HTML form is designed for interactive use, and the contents are listed below. This documentation is essentially identical in content to the 1 Feb 1998 version of the "CFPOST Reference Manual," by The Boeing Company.
