Hello Judy,Â
I do not see anywhere which I can attach a file beside an umage. I used the link share button instead. https://drive.google.com/file/d/1TeS3zPJV-Xm1sNWPYZR8dSetcDmPe4E9/view?usp=drive_link
To keep things simple, the archive file utilizes the opposed-flow_flame__h2_air example that is shipped with ANSYS Chemkin 2023 R2. I have modified the input file to utilize muticompnent diffusion, print level 3 and save transport properties. I have tried viewing the output file in the native Chemkin viewer as well as the Excel output with neither reporting actual values for diffusion coeffiecnts. What I get is:Â
 Mixture_binary_diffusion_coefficients_H2_(cm2/sec) |  Mixture_binary_diffusion_coefficients_H_(cm2/sec) |  Mixture_binary_diffusion_coefficients_O2_(cm2/sec) |
         inf |          inf |          inf |
Hopefully I am missing something simple!Â

Thank you!
