Error in Chemkin and thermo file during creation of flamelet

shyamal · September 12, 2019, 08:03

Hi all,

I am trying to create a flamelet using chemkin.inp and thermo.db. I will use the subsequently generated PDF for non-premixed simulation of turbulent ethylene flame. While importing the chemkin and thermo files it shows an error 'invalid unit data, h, at line no XXX'. Please find attached the snap for reference. Thank you.

Hello, did you find a solution for this? I'm having the same problem

The error in his case is very clear; there is data or reactions for some specie that is missing from the list. Just add the specie in the list or remove its data if the specie is not important.

Well, I am only getting the message: "Invalid UNIT data, h, at line no. 461". I have checked it and H is in the species list so I don't know what's happening.

I have also checked the file chem.out that fluent generates when trying to import a chemkin model and it says that there are no errors in input files.

Could you attach the file here?
