8.15.5. CGNS Files

CFD-Post has limited support for reading meshes and solutions from CGNS (CFD General Notation System) files of version 2.4 or 4.X. Extensions for such files are typically .cgns or .cgs. The following documentation describes the supported and unsupported features of CGNS.


Note:
  • By default, variable names are adjusted to conform to the CFX naming style, which may not always be desirable. To preserve the original variable names in the file, open Edit > Options > CFD-Post > Files and clear Translate variable names to CFX-Solver style names.

  • Only one CGNS file can be postprocessed at a time; multiple simultaneous CGNS files are not supported.
