Wind-US Utilities

In addition to MADCAP, GMAN, and CFPOST, several pre- and post-processing utilities are supplied as part of the Wind-US tools distribution. None of these are required in order to run Wind-US, but may be useful when preparing input files and/or examining the results for a Wind-US run.

Another very useful utility is CGNSview , developed as part of the CGNS project . CGNSview is a viewer/editor for CGNS files (which are similar to Wind-US common files), and allows access to any node in the file using a Windows-like GUI with a collapsible node tree. Nodes and data may be added, deleted, and modified. CGNSview is not part of the Wind-US tools distribution, but instead is part of the CGNStools package, available from http://cgns.github.io/ .

The PDF form of the Wind-US Utilities Guide (1.2M, 97 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 of the Wind-US Utilities Guide is designed for interactive use, and the contents are listed below.

	Supported Utilities
	adf_revert		Convert a common flow (.cfl) file created by Wind-US 3.0 to one that can be read by Wind-US 2.0.
	cfaverage		Average multiple common flow (.cfl) files.
	cfbeta		Add zones to a common grid (.cgd) or common flow (.cfl) file that are symmetric to existing zones.
	cfcnvt		Convert between common files and various other file types.
	cfcombine		Combine multiple structured zones in a common grid (.cgd) or common flow (.cfl) file into a single zone.
	cflistnum		List zone sizes and grid units in a common file.
	cfpart		Partition a single-zone unstructured grid into multiple zones.
	cfreorder		Re-order and/or delete zones in a common grid (.cgd) or common flow (.cfl) file.
	cfreset_iter		Reset the iteration count in a common flow (.cfl) file to zero.
	cfspart		Re-partition unstructured common flow (.cfl) and boundary data (.tda) files.
	cfsplit		Split a structured zone (or zones) in a common grid (.cgd) or common flow (.cfl) file into multiple zones.
	decompose		Split a Wind-US structured grid system and, optionally, the corresponding flow file, into smaller grid zones to improve the parallel processing efficiency.
	fpro		Operate on data in common flow (.cfl) files.
	gpro		Operate on data in common grid (.cgd) files.
	jormak		Find boundary points in a common grid (.cgd) file, and create a journal file containing subset information for CFPOST or PLOT3D.
	mpigetnzone		Get number of zones in a common grid (.cgd) file.
	recombine		Convert a "split" structured common flow (.cfl) file, originally created by decompose, back to the original grid system.
	resplt.pl		Create GENPLOT files containing convergence data from a list output (.lis) file.
	thplt		Create GENPLOT files containing time history data from a time history (.cth) file. This utility must be used with .cth files created using the improved time history capability introduced in Wind alpha 5.52.
	tmptrn		Create a point-by-point wall temperature distribution and/or boundary layer transition data, and write it into the common flow (.cfl) file, for use with Wind-US's TTSPEC keyword.
	USintrpltQ		Interpolate solution from one unstructured grid to another.
	windpar		Compute an estimate of the potential for parallel speed-up of a particular Wind-US case as a function of the number of processors, based on the likely number of grid points per processor.
	Depricated Utilities
	cfappend		Append one common file to another. Use cfcnvt instead.
	resplt.exe		Old Fortran version of the resplt utility used to create GENPLOT files containing convergence data from a list output (.lis) file. The resplt command now defaults to the Perl script (resplt.pl) version of this utility.
	Obsolete Utilities
	adfedit		View (as text) the structure and contents of ADF files. Use CGNSview instead.
	b4wind		Convert between various types of grid and solution files, and/or compute an initial flow field.
	cfnav		Explore the contents of common files via textual output. Use CGNSview instead.
	cfrevert		Convert a common flow (.cfl) file created by Wind-US 2.0 to one that can be read by Wind-US 1.0.
	cfsequence		Remove grid points from a structured common grid (.cgd) or common flow (.cfl) file.
	cfsubset		Remove specified grid points from a structured common grid (.cgd) or common flow (.cfl) file.
	cfunsequence		Add grid points to a structured common flow (.cfl) file.
	cfview		View (as text) the structure and contents of common files. Use CGNSview instead.
	chmgr		Create and manipulate chemistry (.chm) files.
	gridvel		Read the output from a 6DOF program and use that information to set grid velocities in a common grid (.cgd) file.
	timplt		Create GENPLOT files containing time history data from a time history (.cth) file. This utility must be used with .cth files created using versions of the flow solver prior to Wind 5.52.
	usplit-hybrid		Split a single-zone unstructured common grid (.cgd) file into multiple zones. Use cfpart instead.
