Hi everyone,

I'm running into a couple of issues while preprocessing a CHEMKIN input file:

1. Error: Problem finding Arrhenius parameters
   Even though all necessary parameters are present in the input file, I'm still getting this error. Interestingly, the issue seems to occur only with longer or more complex reactions. Shorter reactions don't trigger the error. Could the reaction string length or formatting be causing this?Screenshot of the error:Reaction in the inpot file:

2. Error: MAXORD = 12 must be increased to accommodate this reaction
   It seems like the number of species involved in a single reaction exceeds the default MAXORD limit. How can I manually increase the MAXORD value to allow more reactants/products in a single reaction?Screenshot of the error:

     

Any help or tips would be greatly appreciated!

Thanks in advance!
