ANSYS Forte, starting Arrhenius settings for gasoline and diesel combustion PFI

      I have a student version download and looking to start  modelling the above subject combustion chemistry. I think the only way to start this is to use the Forte materials library, then enter Arrhenius parameters for the two fuels to combustion together. 

      Q1: where can I enter or select Arrhenius reaction model.

      Q2: where can in find parameters inputs for gasoline and diesel Arrhenius inputs?

      In Forte, the reaction data are not manually entered by the user. Instead, the reaction data are stored in a mechanism file and preprocessed as a Chemkin chemistry set file and then imported into Forte. Please refer to the user guide chapter 3.3.1 Chemistry/Materials for details. I'd also recommend that you work through some standard tutorials on modelling gasoline or diesel engines to learn the procedures.

      I have looked at Forte tutorial diesel/ gasoline using sector nesh but with a student software it doesn't work. Now tried selection of diesel and gasoline from the fuel_library.cks file and running tutorial 5 PFI tutorial. Diesel 10% & gasoline 90% with all selections as per tutorial, I think it will crash when ignition CA is reached. Mostly I need to change something in the Flame Speed Model tab. 

       

      Thanks.

      Ren thanks but is there a way in making tutorial chapter 3 duel fuel sector mesh work for academic work? The message I got is that this tutorial can not run on Forte student version.
