Hi guys!
In a transient simulation, if you ask CFX to create CGNS output files, it does it but creates one file each timestep. So if I have 5 timestep I will have 5 files. But Tecplot to work with unsteady simulations wants all the timesteps in one single CGNS file. Do you know if exists a small program/code that can put together all the CGNS files in order to work with Tecplot? Cheers |

From what I understand, either Linux or Windows, all executables need to be ran from the command line. Since I have a Windows machine here, I start up cmd.exe and navigate to where the executable is.
If I do a plot3d_to_cgns -help Then I get all the required arguments and options. So, to actually do my plot3d to cgns conversion, my particular command is ./> plot3d_to_cgns -fc grid.fast flow.fast output.cgns Where -f means formatted text, and -c means convert to primitive variables. After you install just navigate to the folder and do a help on the function to see whats required. |

Hello,
I am new to this forum. Since the discussion was about CGNS, I thought of making a relevant request .I am looking for a working sample C program that can read and write data from an unstructured grid file in CGNS Format. Can anyone help me out with this problem please. Will really appreciate the help. Thanks ![]() |
