  I am working with Plug Flow Reactor in Chemkin 2021 student version. I have to model combustion of premixed methane and oxygen mixtures inside a Platinum tube(Pt being a catalyst for the reaction).
  The chemkin input files are working fine. I have taken them from the existing chemkin sample problems. The boundary conditions that i am giving are referred from a research paper and i am not getting those results.
  The program runs but when you open the post processor, it shows lot of error prompts saying :

  Hi, I am using Ansys Chemkin-Pro 2021 Student License version.nI tried with two sets of boundary conditions(referred from 2 different papers) n1.nSolution doesnt converge.nn2.nThe second case is converging for some values of equivalence ratio(like 0.1, 0.03) and doesnt work for even close values like 0.1077. Also the trends donot match as given in the paper.I have included the chemkin project files along with the input files here.nn
