  3. I am creating an FGM PDF table from one of the Chemkin Model Fuel Libraries. While checking my properties under Species Model, I noticed that the Laminar Flame Speed table is all zeros. What does this mean?

      Laminar flame speed information is embedded in the Model Fuel libraries. To extract this information, the pdf-mixture properties must be set up correctly. To do this, open the pdf-mixture property and change the Laminar Flame Speed property to Laminar-Flame-Speed-Library. Then, generate your PDF table. If your PDF table is already generated, go to Species Model> Properties and click Recalculate Properties. To store this new information in the PDF, resave the PDF after the recalculation.
