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.March 29, 2021 at 10:31 pmRKAnsys EmployeeHello, 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. nMarch 29, 2021 at 11:42 pmEason_23SubscriberHello 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.nMarch 31, 2021 at 11:17 amEason_23SubscriberHello RK,nThank you for your reply. But every time this happened, Fluent turned itself off within seconds, and I didn't have a chance to add material.nMarch 31, 2021 at 11:30 amDrAmineAnsys Employee1/Which mechanism files are you reading?n2/In Which Version?nMarch 31, 2021 at 11:40 amMarch 31, 2021 at 11:50 amDrAmineAnsys EmployeeIs Fluent writing any out files in the directory you are trying to read the mechanism? Can you check them (asc.out, Kineticxxx) nMarch 31, 2021 at 11:51 amDrAmineAnsys EmployeeMechanism looks weird or simple. only one reaction? nMarch 31, 2021 at 11:53 amEason_23SubscriberYes, because the exact mechanism of the reaction is not clear, it's just a simple mechanism.nMarch 31, 2021 at 11:56 amEason_23SubscriberThis is the chem.out file.nnMarch 31, 2021 at 11:57 amDrAmineAnsys EmployeeIt is stating: Mechanism Input Error.nMarch 31, 2021 at 12:00 pmEason_23SubscriberHow can I solve this problem? Because it shuts down automatically every time Fluent is imported.nMarch 31, 2021 at 12:03 pmEason_23SubscriberI have tried Ansys18.2 and 19.2, but the same problems still occur.nMarch 31, 2021 at 12:06 pmDrAmineAnsys EmployeeCan you try reading another mechanism? There are some which are provided in the installation directory of fluent (fluentxx\Kinetics\data)nMarch 31, 2021 at 12:11 pmEason_23SubscriberI have tried, this is the chem.out file. The reaction mechanism is correct, but Fluent still shuts down automatically after import.nnMarch 31, 2021 at 12:19 pmDrAmineAnsys EmployeeI 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).nApril 1, 2021 at 6:51 amEason_23SubscriberHello Amine,nThank you for your reply! But I don't have Ansysr21, can you share your standard mechanism with me? I'd like to try it on ANSYS2020R2.nMany thanks.nnnApril 1, 2021 at 10:22 amEason_23SubscriberHello Amine,nThank you for your reply!
