nithinnm123 is on a distinguished road
I am trying to import data generated external to Fluent using CGNS. The data consists of velocity vectors, temperature, pressure, density, and species mass fractions.

The procedure I have followed :
1. Export an empty mesh (variables were initialized with junk values) form fluent in the form of CGNS.
2. Read the CGNS file in matlab and fill in the variables with the correct data
3. Export to CGNS from matlab

When I try to import this CGNS file into Fluent, only the velocity data is being initialized. I tried importing a CGNS file that was exported using Fluent without any further manipulation, and again only the velocity data is read.

Is there anything that I need to do to make this work? Further, is there a better way to initialize a Fluent case using external data? The data I use is a binary data file, generated using the initialization function of an in-house DNS code.

Software used :
- ANSYS Fluent 2021
- Matlab R2021a with the cgns4m library https://github.com/meshkit/cgns4m
