Applications Software

• CGNS-Compatible Applications
• CGNS Utilities

The development of CGNS-compliant applications, e.g., grid generators, postprocessors, and the like, has not been a direct undertaking of the CGNS team. Rather, it has been the intent to make the attractiveness of interoperable CFD applications, together with general acceptance of the CGNS standard by Boeing, NASA, and others, sufficient to induce applications developers to incorporate CGNS I/O into their offerings.

Several CGNS-compatible applications have indeed been developed, and more continue to appear. This section lists the known applications at the time of publication. Please contact Tony Iannetti to modify or add to the lists.

CGNS-Compatible Applications

This section lists major software packages that read and/or write CGNS files. The software listed here is taken from Table 1 of AIAA Paper 2002-0752, and is for informational purposes only. The CGNS Project Group cannot endorse specific software packages.

CGNS Utilities

A variety of CGNS utility packages have been developed, both by CGNS team members and by CGNS users. While not formally a part of CGNS itself, these utilities are available from the CGNS web site .

	Plot3dg_to_CGNS		Converts a "standard" Plot3D grid file to a CGNS grid file. Contact: Chris Rumsey (Christopher.L.Rumsey@nasa.gov)
	CGNS_to_Plot3d		Converts a CGNS file with a cell-centered solution to "standard" Plot3D grid and solution files. Contact: Chris Rumsey (Christopher.L.Rumsey@nasa.gov)
	CGNS_readhist		Reads a CGNS file and writes history data to a formatted file. Contact: Chris Rumsey (Christopher.L.Rumsey@nasa.gov)
	FTU		Converts CGNS files to and from Plot3D format. Has a text-based menu allowing the manipulation of a CGNS base. Contact: Bob Bush (bushrh@pweh.com)
	CGNSview		A CGNS file viewer and editor; requires Tcl/Tk 8.3 or above. The GUI allows complete editing of CGNS files (both ADF and HDF5), and handles links and data conversions. It works at the CGIO interface level, and thus is not affected by "bad" CGNS files. It includes built-in CGNS node and label information, and documentation support through HTML (including access to all CGNS docs). Contact: Bruce Wedan (leavingdust@gmail.com)
	CGNS Tools		A variety of tools for viewing, editing, and manipulating the contents of CGNS files; requires Tcl/Tk 8.3 or above. Included are: CGNSplot, for plotting grids CGNScalc, a calculator using data in CGNS files Utilities for converting from Patran, and from/to PLOT3D and Tecplot Utilities for modifying the grid location (vertex or cell-center), solution variables (primitive or conservative), and data class (Dimensional, NormalizedByDimensional, or NormalizedByUnknownDimensional) Utilities for creating a subset or interpolated version of a CGNS file These may be used as stand-alone utilities, or initiated from CGNSview, which is included. Contact: Bruce Wedan (leavingdust@gmail.com)
	PyCGNS		A Python binding to the ADF Core and Mid-Level Library. For more information, see the pyCGNS home page . Contact: Marc Poinot (Marc.Poinot@onera.fr)
	ADFM		A development version of software for managing an in-memory representation of ADF trees. Contact: Marc Poinot (Marc.Poinot@onera.fr)
	CGNS++		A C++ binding to the ADF Core and Mid-Level Library. For more information, see the CGNS++ home page . Contact: Manuel Kessler (kessler@iag.uni-stuttgart.de)
