CFD Data (CGNS)
Functions
Using a CFD Data (CGNS) function () you can import CFD analysis data from a CGNS (CFD General Notation System) data file into COMSOL.
The CFD Data (CGNS) function requires the Acoustics Module or the CFD Module and is supported on Windows® only.
Enter a path and name (the complete network path) in the Filename field, or click Browse to locate a library to import. You can also click the downward arrow beside the Browse button and choose Browse From () to open the fullscreen Select File window. Click the Refresh button () to ensure that the file is reread when needed. Click the downward arrow for the Location menu () to choose Show in Auxiliary Data () to move to the row for this file in the Auxiliary Data window, Edit Location () (if the location is a database), Copy Location (), and (if you have copied a file location) Paste Location ().
For each row in the table, the Function name, Arguments, and Function unit appear for the functions in the imported CGNS file.
Go to Common Settings for the Function Nodes for information about the Plot Parameters section.
The Imported Fluid Flow Interface includes dedicated functionality to map and couple the imported CGNS data to a COMSOL Multiphysics mesh and physics.
If you have the Acoustics Module, see Helmholtz Resonator with Flow: Imported Fluid Flow from CGNS Data: Application Library path Acoustics_Module/Aeroacoustics_and_Noise/helmholtz_resonator_with_flow_cgns.
