  I'm trying to import a CHEMKIN reaction mechanism into FLUENT, but there are always some problems, sometimes the FLUENT turns itself off, sometimes it's the same as in the image below.

  Hello, nYou will have to load the species into Fluent, that is what the error is indicating. You can add the missing species from the Fluent database from the Create / Edit Materials. n

  Hello RK,nThank you for your apply. But every time this happened, Fluent turned itself off within seconds, and I didn't have a chance to add material.n

  Is Fluent writing any out files in the directory you are trying to read the mechanism? Can you check them (asc.out, Kineticxxx) n

  Yes, because the exact mechanism of the reaction is not clear, it's just a simple mechanism.n

  How can I solve this problem? Because it shuts down automatically every time Fluent is imported.n

  Can you try reading another mechanism? There are some which are provided in the installation directory of fluent (fluentxx\Kinetics\data)n

  I have tried, this is the chem.out file. The reaction mechanism is correct, but Fluent still shuts down automatically after import.nn

  I am reading one standard mechanism in Fluent Standalone on pipe mesh (generic) everything in butter. So I cannot reproduce the crash on your side (I am using 21R1).n
