Hello, 
I have been trying to open my CGNS file with the corresponding chemistry set in Energico, but when the software tries to load, I get the following error. I would really appreciate it if someone could help me with this.

Which mechanism are you running? What is the sequence of operation leading to this error? Does this happen with all files? 

[Mehdi Salakhi]

This is the sequence of the operation:

1. Export the CFD solution data as CGNS file
2. Loading Ansys Energico
3. Preprocessing my chemistry using Utility in Enegico (which works fine)
4. Selecting working directory, cgns file, and chemistry in Select Files
5. When energico tries to load my data, at half of the way, I get this error

mechanism:

I have been using a reaction mechanism called KAUST (chemistry input + thermodynamics data)

I was able to run energico in another case that had a different CFD solution

I appreciate your help here!

Is there someone that can help me? I got stuck on this problem and it is really urgent! thanks

Hi Mehdi, 

This likely could be related to the local computer. You might want to restart the computer and see if this issue persists. Check the reaction mechanism in notepad to make sure it looks good. 

There could also be a good chance CFD solution export is corrupt. Check with another test case. I hope you are using the newer versions. If all else fails, for a quicker solution, I would suggest to uninstall and reinstall the latest release.

Thank you for your reply. I was just wondering in case my CFD solution export is corrupt, how can I fix this issue for the current CFD data I have?

The reason why I ask here is that somehow I managed to skipp that error, but when I try to load my ckcgns file I get this error:

"Corrupted cell detected at index 46"

If I select Ok, the software proceeds but again at the final step, it couldn't load chemkin for chemical simulation.
