hi
i need simple tutorial for creating chemkin mechanism and importing in fluent
i can work with chemkin and fluent but i dont know how use chemkin with fluent
i know i must import .che format in fluent but i dont know how create .che file
i download .dat mechanism amd therm file from ECR but i dont know how convert this file to . che
please help

Since you already know hoe to work with chemkin, you can directly import the mechanism files to fluent using the File > Import > Chemkin mechanism ...

You do not need to change the file format. If the files worked with Chemkin preprocessor, then they are in correct format to import. btw Fluent will only work with mechanism with 50 species or less.

Example here: http://aerojet.engr.ucdavis.edu/flue...g/node1301.htm

I guess you need to use reduced mechanisms.
Or you can eliminates some of the reactions (for instance, N2 reactions) by assuming it's an inert if you have the right problem statement.
